1.	Which of the following does it increase the rate of catalyst?(a) Decreasing Ea(b) Increasing Ea(c) Increasing pressure(d) Increasing entropyThis question was posed to me during an online exam.This interesting question is from Surface Chemistry topic in portion Surface Chemistry of Chemistry – Class 12
Answer» The correct choice is (a) Decreasing Ea Easy EXPLANATION: A CATALYST lowers the activation ENERGY and so more PARTICLES can attain activation energy, thus a faster rate of reaction. Only a small amount of catalyst is required. Increasing the amount of catalyst used will not increase the rates of reaction beyond a certain POINT.
