Question

The rate law for a reaction between the substances A and B is given by Rate = k [ A ] n [ B ] m On doubling the concentration of A and halving the concentration of B, the ratio of the new rate to the earlier rate of the reaction will be as

TestHub · Accepted Answer

Rate 1 ​ = k [ A ] n [ B ] m ; Rate 2 ​ = k [ 2 A ] n [ 1/2 B ] m ∴ Rate 1 ​ Rate 2 ​ ​ = k [ A ] n [ B ] m k [ 2 A ] n [ 1/2 B ] m ​ = [ 2 ] n [ 1/2 ] m = 2 n ⋅ 2 − m = 2 n − m
