1.	The minimum amount of energy needed to start a reaction is called the ______(a) Activation energy(b) Energy of reaction(c) Entropy of reaction(d) Reaction mechanism energyThis question was posed to me in final exam.The above asked question is from Concentration Gradients and Reaction Rates in Solid Catalysts in division Heterogenous Reactions of Bioprocess Engineering
Answer» Correct option is (a) ACTIVATION energy Easiest explanation: Activation energy is the MINIMUM energy required for a reaction to occur. Catalysis is the increase in the rate of a CHEMICAL reaction by LOWERING its activation energy. TRANSITION state is an intermediate state during a chemical reaction that has a higher energy than the reactants or the products.
