Question

The rate equation for the reaction 2A + B

\to

C is found to be a : r = k[A][B]. The correct statement in relation of this reaction is that the

Options:

A . Rate of formation of C is twice the rate of disappearance of A

B . t12 is a constant

C . Unit of k is s−1

D . Value of k is independent of the initial concentration of A and B

Answer: Option D
:
D
The order of the reaction is two. Option (b) and (c) apply to first order reactions. Options (a) is wrong since the rate of formation of C is half the rate of disappearance of A. Option (d) is always true since value of k for any order is independent of the initial concentration of the reactants.
