試題詳解

28. At a certain temperature, cis-1,2-dimethylcyclopropane (M) and trans-1,2- dimethylcyclopropane (N) undergo the following transformation.

The rate laws for the reactions can be expressed as , with ky and k, being constants at a given temperature, called the forward and reverse rate constants, respectively, and the equilibrium constant of the reaction, K = 3. Which of the following statements is correct?
(A) At this temperature, the conversion of M is 66.7%.
(B) As the temperature increases, both , increase.
(C) At room temperature, N is a gas under 1 atm.
(D) M is more stable than N.
(E) Heating this reaction increases the equilibrium constant K.
