For a certain reaction, the rate = k [A]2 [B], when the initial concentration of A is tripled keeping concentration of B constant, the initial rate would (A) increase by a factor of six (B) increase b

Question

For a certain reaction, the rate = k [A]2 [B], when the initial concentration of A is tripled keeping concentration of B constant, the initial rate would

(A) increase by a factor of six
(B) increase by a factor of nine
(C) increase by a factor of three
(D) decrease by a factor of nine

Prashant Kotian · Accepted Answer

Correct answer: B. Rate = k [A]2 [B] If [A] is tripled and [B] is kept constant. r1 = k [3A]2 [B] r1 = 9k [A]2 [B] r1 = 9r Increased by a factor of nine
