Answer:
increase the concentration of A by 40% approximately.
Explanation:
The rate of reaction is directly proportional to square of the concentration of chemical present A. the rate of reaction is inversely proportional to concentration of B. Thus we can write it as :
Rate = K [A]²[B]⁻¹
Now if we are increasing the concentration of B by 100% it means we are doubling its concentration.
If we wish to keep the rate of reaction constant we have to increase the concentration of A
Rate =K [A₁]²[B₁]⁻¹ = K [A₂]²[B₂]⁻¹ =K [A₂]²[2B₁]⁻¹
K [A₁]²[B₁]⁻¹ = K [A₂]²[2B₁]⁻¹
[A₁]² = 0.5 X [A₂]²
[A₂] = 1.414 [A₁]
It means we have to increase the concentration of A by 40% approximately.
