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.
