The plot shows the variation of −ln Kp versus temperature for the two reactions.

Question

Identify the correct statement

$\begin{array}{1 1}(1) At \;T > 1200\; K,\; carbon\; will\; reduce\; MO(s)\; to\; M(s).\\ (2)At\; T<1200 K,\; the\; reaction \; MO(s)+C(s) \to M(s)+CO(g)\; is\; spontaneous. \\ (3) At\; T<1200\; K, oxidation\; of\; carbon\; is\; unfavourable. \\ (4)\text{Oxidation of carbon is favourable at all temperatures.} \end{array}$</span>
