4. When the following reaction is at equilibrium, which of these relationships is always true? 2O3(g) 3O2(g)
a. [O3] / [O2]
b. [O3]2/ [O2]3
c. Kc=[O3]2/ [O2]3
d. Kc= [O2]3 /[O3]2

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall. (use the words "first, second, third, fourth" to fill each blank)experimentinitial conc of a, mol/l initial conc of b, mol/l initial conc of c, mol/l initial rate, mol/l.s1 0.1 0.1 0.2 2 x 10-32 0.2 0.3 0.2 6 x 10-33 0.3 0.1 0.2 2 x 10-34 0.4 0.3 0.4 1.2 x 10-2
