Consider the elementary reaction sequence shown in figure. Which of the following equations are correct ?

Options

A. `(d[A])/(d t) = -k_(1)[A] + k_(4)[D]`
B. `(d[C])/(d t) = k_(2)[B] - k_(3)[C]`
C. `(d[D])/(d t) = -k_(4)[D] + k_(3)[D]`
D. Nothing can be said about order of reactions in this problem.

Answer

B

Explanation

In given sequence of reaction `(d[C])/(d t) = k_(2)[B] - k_(3)[C]`
