Answer» Correct Answer - B (II)Rate of Rxn=Rate of formation of C They we say by I data. Suppose `["Rate"=k[A]^a[B]^b]`…(i) `1.32xx10^(-4)=k[.10]^a[.05]^b`…(ii) `2.6xx10^(-4)=k[.10]^a[.10]^b`…(iii) `1.02xx10^(-3)=k[.20]^a[.10]^b`…(iv) By equation (ii) and (iii) we find b=1 By (iii) and (iv) we find `a=2.97~~3` Then Rate `=k[A]^3[B]^1` |
