When the following reaction is at equilibrium, which of these relationships is always true?
2 O3(g) 3 O2(g)

A. [O3]2 = [O2]3

B. Kc[O2]2 = [O3]3

C. [O3] = [O2]
D. Kc[O3]2 = [O2]3

E. Kc[O2]3 = [O3]2

  • chemistry -

    Kc = (O2)^3/(O3)^2. Look at how this can be rearranged to find the right choice.

  • chemistry -

    C
