The plot shows the variation of -InK_(p) versus temperature for the two reactions. M(s)+(1)/(2)O_(2)(g)toMO(s)andC(s)+(1)/(2)O_(2)(g)toCO(s) Identify the correct statement :

Answer»

At `Tlt1200K`, oxidation of CARBON is unfavourable.
Oxidation of carbon is favourable at all temperatures.
At `Tgt1200K`, the REACTION `MO(s)+C(s)toM(s)+CO(g)` is spontaneous.
At `Tgt1200K`, carbon will REDUCE MO(s) to M(s).

Solution :
At `Tlt1200K`, carbon will reduce MO(s) to M(s) HENCE, chemical reaction
`MO(s)+C(s)toM(s)+CO(g)` is spontaneous.
