Consider the following reaction: 3A → 2B
The average rate of appearance of B is given by Δ[B]/Δt.Comparing the rate of appearance of B and the rate of disappearance of A,we get

Quizplus · Accepted Answer

According to the given reaction, 3 moles of A react to form 2 moles of B. Therefore, the rate of disappearance of A is (Δ[A]/Δt) = -3/2 times the rate of appearance of B (Δ[B]/Δt). Therefore, the ratio of the rate of appearance of B to the rate of disappearance of A is:

Δ[B]/Δt ÷ Δ[A]/Δt = Δ[B]/Δ[A] = 2/3

Thus, the rate of appearance of B is 2/3 times the rate of disappearance of A. Therefore, the answer is B.
