Question

The rate of the reaction 3A + 2B -> Products is given by the rate expression: rate = K [A] [B]^2. If A is taken in large excess, the reaction start obeying

Prashant Kotian · Accepted Answer

Correct answer: B. If A is in large excess, its concentration remains virtually constant during the reaction. Thus, rate = K' [B]^2 where K' = K [A]. The reaction start obeying second-order kinetics.
