Question

In 2nd order reaction 2OH →→ H2O + O k = 1.47 x 1010 M-1 s-1. There is an initial OH concentration of [OH]0 = 1.88×10−4M. which takes 3.77 x 10^-7s for the oxygen concetration to decrease to 6.0997×10−5M.

b) At time 3.77 x 10^-7s, what will the oxygen concetration be?

Expert Solution
Step 1

Provided 2nd order reaction

2OH → H2O + O

Rate constant, k = 1.47 x 1010 M-1 s-1

Initial concentration, [OH]0 = 1.88×10−4M

Time, t=3.77 x 10-7 s

Final concentration. [OH]=?
