Answer: c. ΔH˚ is positive and ΔS˚ is positive
Explanation:
According to Gibb's equation:
= Gibbs free energy
= enthalpy change
= entropy change
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Thus for 
Case :
>
when 
both have positive values.
Reaction is spontaneous only at at high temperatures.
