Question

In the reaction 2A --> B+ 3 C, rate of disappearance of A is 3 mol |^-1 s^-1, what will be rate of formation of C?​

Answer 1

Explanation:

The value of k is independent of the initial concentration of A and B.

From the rate equation rate =k[A][B], we can say that the reaction is first order in A and first order in B. Hence, the overall order of the reaction is 2.

(A) The value of k is independent of the initial concentration of A and B. Hence, the statement B is correct.

(B) The half life period is not constant. It is inversely proportional to the concentration of reactants. Hence, the statement B is incorrect.

(C) The rate of formation of C is one half the rate of disappearance of A.

dt

d[C]

=

2dt

−d[A]

Hence, the statement C is incorrect.

(D) The unit of k must be mol

−1

s

−1

Hence, the statement D is incorrect.
