The plot shows the variation of \(- In\,K_p\) versus temperature for the two reactions. \(M(s) + \frac{1}{2}{O_2}(s)\, \to \,MO(s)\,\) and \(C(s) + \frac{1}{2}{O_2}(g)\, \to \,CO(s)\,\) Identify the correct statement
- A At \(T < 1200\,K,\) oxidation of carbon is unfavourable
- B Oxidation of carbon is favourable at all temperatures.
- C At \(T< 1200\,K,\) the reaction \(MO(s) +C(s) \to M(s) + CO(g)\) is spontaneous.
- D At \(T > 1200\,K,\) carbon will reduce \(MO(s)\) to \(M(s)\)
Answer & Solution
Correct Answer
(C) At \(T< 1200\,K,\) the reaction \(MO(s) +C(s) \to M(s) + CO(g)\) is spontaneous.
Step-by-step Solution
Detailed explanation
At \(< 1200\,K\), carbon will reduce \(MO(s)\) to \(M(s)\) hence, chemical reaction \(MO(s) + C(s) \to M(s) + CO(g)\) is spontaneous
