if the Kc for the reaction 2so2(g)+o2(g)⇌2so3(g) is 1.30×10^12 at 500 K. Calculate the Kc For the reactions (i) SO2(g) +1÷2O2(g)⇌SO3(g) (ii)SO3(g)⇌ 2SO2(g) + O2(g) at the same temperature.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
