Question

Which of the following changes will always be true for a system with increasing entropy? –ΔG –ΔH +ΔG +ΔS

Answer 1

Answer: The correct answer is $+\Delta S$

Explanation:

From the given options:

$\Delta G$ represents the change in Gibb's Free energy of the reaction. If this value is negative, the reaction is said to be spontaneous and if the value is positive, the reaction is said to be non-spontaneous.

$\Delta H$ represents the change in enthalpy of the reaction. If this comes out to be negative, then the reaction is said to be exothermic and if it comes out to be positive, then the reaction is said to be endothermic.

$\Delta S$ represents the change in entropy of the reaction. If this comes out to be positive, then it means there is increase in entropy and if this comes out to be negative, then it means there is decrease in entropy.

Hence, the correct answer is $+\Delta S$
