- Q: Is the catalyst considered a chemical reaction?
- The middle school textbook defines that the catalyst itself does not participate in chemical reactions
- Q: The addition of the catalyst has no effect on the chemical equilibrium of the movement
- Factors that affect the chemical balance of movement are mainly concentration, temperature, pressure and so on.
- Q: Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- Q: Chemistry teaching and learning a bit difficult, thank you
- Palladium Pd, platinum Pt as a catalyst
- Q: What is a catalyst in a chemical reaction?
- Hi Ganah! A catalyst is a substance that increases the rate of a chemical reaction without itself being used up in the reaction. They lower the activation energy for a reaction and also speed up the rate of the reaction (both in reverse and forward reactions). Let's look at a generic chemical reaction: A + B---C + D C + D---B + E Here, the catalyst is substance B because it is part of the chemical reaction but then it is not used up in the net reaction. See how it seems to be used up in the first step, but by the second step, the catalyst is made once again. The net reaction is A + B--->B + E and you can see how it is not consumed in the reaction. There are also 3 types of catalysts. Heterogeneous catalysts are catalysts that are in different phases than the reactants. An example would be like a reaction between two solids but a liquid is added to speed up the reaction. The liquid is in a different state of matter than the solids but it can still function as a heterogeneous catalyst. Homogeneous catalysts are catalysts that are in the same states of matter as the reactants. An example would then be ethyl acetate reacting with water to form acetic acid and ethanol with an acidic catalyst. They would all be liquids. Lastly, there are enzyme catalysts. These are proteins in your body that speed up biological reactions by reacting with substrates. I hope this helped and good luck with chem!
- Q: Could you please explain it, i know they increase reaction rates but how?
- A catalyst provides an alternative route for the reaction, (maybe more steps than previously), but each step having a lower activation energy than the original uncatalysed reaction. This means that although there will be the same number of collisions per second (if the reaction is performed at the same temperature as before), a greater fraction of those collisions will result in a reaction - so there will be more reactions per second. In the case of a heterogeneous catalyst - e.g. a solid surface the change is that the first step is a bond to the surface which waekens some of the bonds in the reactants - again making a greater fraction of reactions result in reaction.
- Q: Explain how a catalyst may increase the rate of chemical reaction?
- A catalyst lowers the acitvation energy of a reaction.
- Q: The chemical reaction equation of methanol heating and oxygen in the presence of catalyst
- 2CH3OH + O2 === 2HCHO + 2H2O
- Q: Several experiments were carried out using catalysts
- Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
- Q: I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.
- ok its not catalyst converter its catalytic converter. next i have not read one answer that is correct a couple are close but no cigar. ok the 02 sensor senses the oxygen content in the exhaust gasses. using the oxygen content it can determine if the engine is running to rich or to lean. the ecm (computer) wants to keep the engine at optimum fuel mileage or keep it stoichometric meaning fuel to air ratio of 14.7:1 the ecm can adjust fuel air ratios by changing the pulse width and the duty cycle or on off time of the injector.it also uses several other sensors to help it like intake air temp (iat) coolant temp (cts) mass air readings if equipped (MAF) or manifold absolute pressure (map) so its not just the oxygen sensor it can make adjustments as need. anyways the oxygen sensor uses a .1 to .9 volt range signal anything below .450 is lean anything above .450 is rich and .4 to .5 is perfect. but ur engine constantly changes and the 02 readings change constantly new cars can take readings as fast as one or two times a second older cars are alittle slower. anyways only replace the 02 sensor if the car is telling u its bad meaning u have a check engine light on and a code that says P 0 . . . bank one sensor one ckt malfunction or bank 2 sensor 1 ckt malfunction u get the idea unless that happens ur 02's are good leave them alone. when they do go bad ur car will run rich and puke alittle black smoke out the exhaust and ur car will smell like rotten eggs. NOW the cat its job is to heat up to 600 + degreees F and burn unburnt fuel from the combustion cycle of the engine when an engine does not burn all its fuel its running rich and bad fuel milage occurs. if the 02 sensor goes out it can heat the cat red hot as the extra fuel being burnt inside it can become extremely hot. most 02 sensor for most vehicles run around 60 bucks not expensive. a car can have 1 to 4 of these and YES if bad and left for too long and can ruin a cat converter.
