For an endothermic reaction the value of ΔS is positive.The reaction is
Options
(a) feasible when ΔH > TΔS
(b) feasible when TΔS > ΔH
(c) feasible at all temperatures
(d) not feasible at all
Correct Answer:
feasible when TΔS > ΔH
Explanation:
According to Gibb’s equation,
ΔG = ΔH – TΔS.
Therefore for ΔS to be positive, therefore for feasibility of the reaction is possible only if TΔS > ΔH so that ΔG = -ve.
