Correct option is C
The thermodynamic quantity of the system, the decrease in whose value during a process is equal to useful work done by the system i,e., ΔG=ΔH−TΔS, H= enthalpy S= entropy and T= absolute temperature. If an endothermic reaction occurs spontaneously i.e ΔH=+ ve then for reaction to be spontaneous ∆G should be negative that is only possible when ΔS>0 at constant temperature and pressure.Talk to our academic expert!
