Question

The following information is available for the reaction R → P: R → P; rate = r₁, R(catalyst A) → P; rate = r₂, R(catalyst B) → P; rate = r₃, R(catalyst C) → P; rate = r₄, R(catalyst D) → P; rate = r₅, R(catalyst A+C) → P; rate = r₆, R(catalyst A+D) → P; rate = r₇. If r₃ < r₁ = r₄ = r₅ < r₇ < r₂ < r₆, then the only incorrect statement is

Prashant Kotian · Accepted Answer

Correct answer: D. Here, r₄ = r₁ means C alone is not a catalyst. r₆ > r₂ means C increases the activity of A, so C is a promoter for A. A does not promote C, but rather A acts as the main catalyst while C promotes it. So, stating "A is a catalytic promoter of C" is incorrect. Therefore, correct answer is D.
