In which statement is true ?

Options

A. Reaction `A + B rarr Q` is faster.
B. Reaction `Q rarr C` is faster.
C. Reaction in (a) and (b) are equal.
D. Unpredictable.

Answer

B

Explanation

Since `E_(a)` for the reaction `A + B rarr Q (25-7 = 18 kcal mol^(-1))` is greater than `E_(a)` for the reaction `Q rarr C (3 kcal mol^(-1))`. Therefore, reaction `QrarrC` is faster.
