Match List I (Equations) with List II (Type of processes) and select the correct option.

List I		List II
Equations		Type of processes
A.	Kp > Q	(i)	Non- spontaneous
B.	$$\Delta $$Go < RT ln Q	(ii)	Equilibrium
C.	Kp = Q	(iii)	Spontaneous and endothermic
D.	T > $${{\Delta H} \over {\Delta S}}$$	(iv)	Spontaneous

The following two reactions are known

Fe₂O_3(s) + 3CO_(g) $$ \to $$ 2Fe_(s) + 3CO_2(g); $$\Delta $$H = $$-$$ 26.8 kJ

FeO_(s) + CO(g) $$ \to $$  Fe_(s) + CO_2(g); $$\Delta $$H = $$-$$ 16.5 kJ

The value of $$\Delta $$H for the following reaction

Fe₂O_3(s) + CO_(g) $$ \to $$  2FeO_(s) + CO_2(g) is
