CADEMIY 73 law for a reaction between the substances A and B is given by rate = K[A]" [B. On The rate law Chemicalkinetics doubling the concentration ofA and halving the concentration of B, the ratio of the new rate to tne earlier rate of the reaction will be as W rate to the (a) 1/2m +n cian (O 15-17 (b) (m + n) (c) (n- m) (d) 2(n-m)
