equation 1--reverse it and take 1/2. Then Kc for the new rxn is 1/sqrt Kc = k1
equation 2--reverse it. Kc for new reaction is 1/Kc = k2.
Add the two new equations to obtain the desired equation.
Kc for the new equation is k1*k2.
Using this data,
2 NO(g) + Cl2(g) == 2 NOCl(g) Kc = 3.20 X 10-3
NO2(g) == NO(g) + ½ O2(g) Kc = 3.93
calculate a value for Kc for the reaction,
NOCl (g) + ½ O2 (g) == NO2 (g) + ½ Cl2 (g)
