ΔG is always positive when enthalpy increases and entropy decreases. Option D.
What is ΔG?
It is known as Gibb's free energy of systems. It is calculated from the combination of the enthalpy (ΔH), entropy (ΔS), and temperature (T) of systems.
The variables are related together in Gibb's free energy equation as follows:
ΔG = ΔH - TΔS
From the equation above, in order for ΔG to be positive, the product of the temperature and the entropy must be greater than the enthalpy.
Thus, in order to have a chance of positive ΔG, the enthalpy must be increasing while the entropy must be decreasing.
