QAIPM-2012-Ch-1690: NEET 2012 Chemistry - Class 11 AIPM-2012-Ch-1690 Solution: In which of the following reactions standard reaction entropy…

In which of the following reactions standard reaction entropy change (ΔS∘\Delta S^\circ) is positive and standard Gibb's energy change (ΔG∘\Delta G^\circ) decreases sharply with increasing temperature? C(graphite)+12O2(g)→CO(g)C(\text{graphite}) + \frac{1}{2}O_2(g) \rightarrow CO(g) CO(g)+12O2(g)→CO2(g)CO(g) + \frac{1}{2}O_2(g) \rightarrow CO_2(g) Mg(s)+12O2(g)→MgO(g)Mg(s) + \frac{1}{2}O_2(g) \rightarrow MgO(g) 12C(graphite)+12O2(g)→12CO2(g)\frac{1}{2}C(\text{graphite}) + \frac{1}{2}O_2(g) \rightarrow \frac{1}{2}CO_2(g)
