Question

Consider the following reaction, the rate expression of which is given below

A + B \to C rate = k [A]^{1/2} [B]^{1/2}

The reaction is initiated by taking

1 M

concentration of

A

and

B

each. If the rate constant

(k)

is

4.6 \times 10^{- 2} s^{- 1}

, then the time taken for

A

to become

0.1 M

is_____ sec. (nearest integer)

Accepted Answer

Correct answer: 50. (50) K= 2.303t log ⁡ 10.14.6 10^-2= 2.303tt=50 sec .
