Answer to Question #118131 in Inorganic Chemistry for Angelina

Question

1. Use the following information to answer the next question. In a chemical reaction, the reactants combine to form the final product. Before making the final product, they form an intermediate complex: C + D -> C – D -> E The reactants C and D form intermediate molecule C – D and then molecule E. The enthalpy change of reaction does not depend on the?

A. the state of reactants and products

B. nature of reactants and products

C. nature of the intermediate molecules

D. nature od C, D and E

E. initial and final enthalpies of the reaction

2.If the rate law for a hypothetical reaction is r = k[A]^2[B]^1, what is the order of reaction with respect to A?

Answer 1

1

Enthalpy change does not depend on the state of the intermediate molecules

2.

$\ r = k[A]^2[B]^1$

It means the order of the reaction with respect to A is 2 and with respect to B it is 1

and hence the total order of the reaction is 2+1 =3
