Question

10.Which of the following statements concerning kinetics is true?
A.Raising the temperature usually slows the rate ofreaction.
B. Fasterreactions have higher activation barriers than slowerreactions.
C. In asecond-order reaction with a rate law of rate = k[A][B], increasingthe concentration of either A or B will increase the rate ofreaction.
D. In asecond-order reaction with a rate law of rate = k[A][B], doublingthe concentration of both A and B will double the rate ofreaction.
E. Therate of reaction is generally fastest for reactions that areendothermic.

Explanation / Answer

   The following statements are true with respect toKinetics of the Reaction :      In a second-order reaction with arate law of rate = k[A][B], increasing the concentration of eitherA or B will increase the rate of reaction.
     The option is c is onlycorrect statement.     Raising the temperature usually increasesthe Rate of a Reaction.     Faster Reaction have lower Activationenergy , So that they will form the product at thefaster Rate.      In Second order Reaction by doublingthe concentration of the Reactants the Rate of the Reaction becomesfour times.      The endothermic Reactioninvolves absorption of heat so as to form the products so the Rateof the Reaction is usually       slower when compared toExothermic Reaction.
