#### The rate equation for the reaction is found to be : rate The correct statement in relation to this reaction is that the Option 1) unit of must be s-1 Option 2)   is a constant Option 3) rate of formation of is twice the rate of disappearance of Option 4) value of is independent of the initial concentrations of   and

As we learnt in

First Order Reaction -

The rate of the reaction is proportional to the first power of the concentration of the reaction

- wherein

Formula:

R            P

a                 0

a-x             x

[differentiate rate law]

Unit of

rate= k[A] [B]

According to rate law equation order of reaction with respect to A and with respect to B is first order so value of k is independent of the initial concentration of A and B.

Option 1)

unit of must be s-1

Incorrect Option

Option 2)

is a constant

Incorrect Option

Option 3)

rate of formation of is twice the rate of disappearance of

Incorrect Option

Option 4)

value of is independent of the initial concentrations of   and

Correct Option
