The rate law for a reaction between the substances A and B is given by Rate=k[A]n[B]m\text{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 a. m+nm + n b. (n−m)(n - m) c. 2(n−m)2^{(n-m)} d. 12(m+n)\frac{1}{2^{(m+n)}}
