Question

The reaction MgO ( s ) + C ( s ) → Mg ( s ) + CO ( g ) , for which Δ H ∘ = + 491.1 kJ mol − 1 and Δ S ∘ = 198.0 JK − 1 mol − 1 is not feasible at 298 K . Temperature above which reaction will be feasible is

TestHub · Accepted Answer

MgO ( s ) + C ( s ) → Mg ( s ) + CO ( g ) For a reaction to be spontaneous Δ G < 0 Δ H ∘ − T Δ S ∘ < 0 ⇒ T > Δ S ∘ Δ H ∘ T > 198 491.1 × 1000 T > 2480.3 K
