is 1.2 x 10^3 atm s1. What is the average rate for disappearance of O3?
1 Answer

Using the balanced coefficients in the equations we know how to relate the rate, d/dt, of product to a reagent;
(1/3)d(O2)/dt = 1/2(d(O3)/dt)
therefore,
d(O3)/dt = (2/3)d(O2)/dt = (2/3)(1.2×10^3 atm/s) = 8.0×10^4 atm/s
