Question

If A→B, (rB) = k1CA^2 and A→C, (rC) = k2CA^1, then the yield of C is ____

(a) \(\frac{k_2}{k_2+k_1 C_A} \)

(b) \(\frac{k_2}{k_2+k_1} \)

(c) \(\frac{1}{k_2+k_1 C_A} \)

(d) \(\frac{k_2}{k_1 C_A} \)

I got this question in a job interview.

The doubt is from Parallel Reactions Design topic in chapter Potpourri of Multiple Reactions, Design for Single & Parallel Reactions of Chemical Reaction Engineering

Answer 1

Correct choice is (a) \(\frac{k_2}{k_2+k_1 C_A} \)

Best explanation: Yield of C = \(\frac{k_2 C_A}{k_2+k_1 C_A^2} \)

Yield of C = \(\frac{k_2}{k_2+k_1 C_A} \)
