For a reaction A+BrarrP , the rate is ...

For a reaction `A+BrarrP` , the rate is given by Rate `=k[A][B]^(2)`
How is the rate of reaction affected if the concentration of B is doubled ?

Text Solution

Verified by Experts

(i) As the reaction is second order w.r.t B, doubling the concentration of B will double the rate of the reaction.
(ii) If A is present in large excess, then its concentration with remain constant during the course of the reaction and the reaction will then become second order with respect to B.
