7.33. The value of Kc for the reaction 3O2(g) ⇌2O3(g) is 2.0 x 10-50 at 25°C. If equilibrium concentration of O2 in air at 25°C is 1.6 x 10-2, what is the concentration of O3?
7.33. The value of Kc for the reaction 3O2(g) ⇌2O3(g) is 2.0 x 10-50 at 25°C. If equilibrium concentration of O2 in air at 25°C is 1.6 x 10-2, what is the concentration of O3?
The equilibrium constant expression is
Kc = [O3]2 / [O2]3
2.0*1050 = [O3]2 / (1.6*102)3
[O3]2=2.0*1050* (1.6*102)3
=8.192*1056
Hence, the equilibrium concentration of ozone is
[O3]= 2.86*1028M
