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, the percentage fractional yield of product B is strictly formulated as:

Prashant Kotian · Accepted Answer

Correct answer: C. For competing parallel pathways occurring at identical reaction orders, the ratio of the products formed heavily depends on the ratio of their specific rate constants. The total consumption rate depends on . Therefore, the fractional yield of B is identically .
