Question

The experimental data for the reaction, 2A + B₂ → 2AB is 

The rate equation for the above data is

(a) Rate = k [A]²[B]²

(b) Rate = k [A]²[B]

(c) Rate = k[B₂]

(d) Rate = k[B₂]²

Answer 1

Correct option (c) Rate = k[B₂]

Explanation :

For the reaction 2A + 

B₂ ⇋ 2AB, Rate = k [A]^x[B₂]^y 

On substituting the given data, we get 

On dividing equation (iii) by (ii), we get ,

Answer 2

Option C is correct

The rate does not change with change in concentration of A but it is doubled when concentration of B₂ is doubled.
