The reaction a → products was found to be second order order and have a rate constant, k, of 0.707 m-1 s-1. if the initial concentration of the reaction was 0.737 m, what is the half life for the reaction?

Half-life for the reaction is 1.92s

Explanation:

Integrated rate equation for the given second order reaction is-

Where is concentration of A after "t" time and is initial concentration of A

At half-life,

Here and

Plug-in all the values in the above equation-

or,

or,

or,

So, half-life for the reaction is 1.92s

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck
