1. The rate of reaction------------as the reaction proceeds. a) Increases b) Decreases c) Remains the same d) May increase or decrease ... Answer is b) Explanation: Rate of reaction is directly proportional to concentration of reactants. As reaction proceeds, the concentration of reactant decreases, so rate of reaction also decreases. show Answer 2. The unit of the rate constant is the same as that of reaction in------------order reaction. a) First b) Second c) Third d) Zero ... Answer is d) Explanation: In zero order reaction, the rate of reaction is independent of concentration of reactant, So rate of reaction and rate constant are equal, so their units are also same. Consider a reaction, A .......> B If this reaction is a zero order, then rate equation can be derived as follow: Rate of reaction ∝ [A] 0 Rate of reaction = K [A] 0 Rate of reaction = K show Answer 3. For the reaction, ...
