Question

A highly reactive chemical species A simultaneously undergoes two distinct parallel first-order reactions to form B (rate constant $k_1$) and C (rate constant $k_2$). At any given timestamp, what is the percentage fractional yield of product B?

Prashant Kotian · Accepted Answer

Correct answer: C. For competing parallel pathways of the same order, the ratio of products depends on the ratio of their rate constants. The total rate of decomposition of A is governed by . Therefore, the fraction converted to B is strictly .
