Physical Chemistry Question on Kinetics
Which one of the following is a rate equation for second order bimolecular reaction if, a and b are the initial concentrations of A and B, respectively, and x is the concentration of each species reacting in time t and k is second‐order reaction
A
k = [2.303/ t(a − b)] x [log a(a − x) / b(b − x) ]
B
k = [2.303/ t(a − b)] x [log b(a − x) / a(b − x) ]
C
k = [2.303/ t(a − b)] / [log b(a − x) / a(b − x) ]
D
k = [2.303/ t(a − b)] / [log a(a − x) / b(b − x) ]
Answer
k = [2.303/ t(a − b)] / [log b(a − x) / a(b − x) ]
Explanation
Solution
The correct option is (C): k = [2.303/ t(a − b)] / [log b(a − x) / a(b − x) ]
