MCAT Question of the Day


  • Q:

    A particular reaction can be simplified to the following form: A -> B + Heat (i.e. an exothermic reaction). Assume that the reaction occurs in a closed environment. Say that the forward rate of the reaction is k1 and the reverse rate of the reaction is k-1. If temperature of the system was decreased, what would be the expected effect on k1 and k-1?

     

    A

    k1 increases, k-1 decreases

    B

    k1 decreases, k-1 increases

    C

    Both k1 and k-1 decrease

    D

    k1 and k-1 remain constant.
