Option (a) is correct as according to Gibb's free energy equation ΔG = ΔH - TΔS.
Now if. ΔH = —ve (as given in option (a)) (at low temperature) and ΔS = +ve.
then ΔG = -ve (spontaneous)
option (b) is correct if
ΔH = +ve (as given in option (b)) and ΔS = +ve. Also if ΔS > ΔH (conditional), then ΔG = -ve (spontaneous)
Option (c) is correct
If ΔS = —ve (as given in option (c)) and ΔH = -ve. Also ΔH > ΔS (conditional) then. ΔG = -ve (spontaneous)
