From the equation ΔG = ΔH - TΔS, it can be concluded that ...

A. the capacity of a system to perform useful work is related to the total free energy of the system

B. increasing the temperature of a system will increase the probability of spontaneous change

C. increasing the change in entropy of a system will increase the probability of spontaneous change

D. all of the other answer choices are true

D. all of the other answer choices are true

Explanation:

In thermodynamics, Gibbs free energy ΔG refers to the amount of energy in a fluid system which can be converted into non mechanical work at constant temperature and pressure.

It can be calculated using the equation ΔG = ΔH - TΔS

the sum of enthalpy ΔH

the product of temperature and entropy TΔS.

ΔG < 0, the reaction is spontaneous

ΔG > 0, the reaction is non spontaneous

ΔG = 0, the reaction is at equilibrium

Therefore all the the three statements are true. An increase in temperature and entropy will increase the probability of a spontaneous change.

All of the above is true so option D is correct.

The conclusion that: the capacity for work to be done is related to the total free energy in a system, a temperature increase will increase the probability of spontaneous change, the increase in entropy change will increase the probability of spontaneous change are all true.
