All the given reaction are carried out at constant pressure and temperature conditions. Assuming ideal behavior of all the gases involved.

Column-1	Column-2	Column-3
(I)	2Ag2O(s) ⎯→ 4Ag(s) + O2(g)	(i)	wrxn > 0	(P)	Reaction is spontaneous at high temperature.
(II)	2CO(g) + O2(g) ⎯→ 2CO2(g)	(ii)	wrxn < 0	(Q)	Reaction is spontaneous at all temperatures.
(III)	2C(s) + O2(g) ⎯→ 2CO(g)	(iii)	ΔrxnH > 0	(R)	Reactant mixture is diamagnetic.
(IV)	N2(g) + 3H2(g) ⎯→ 2NH3(g)	(iv)	ΔrxnS > 0	(S)	One of the reactant is used to reduce metallic oxide in to metal.

(i) The only incorrect combination is –
