Question

In a spontaneous change, which of the following is true?

Entropy always decreases.

Temperature always increases.

Gibbs free energy always decreases.

Gibbs free energy always increases.

Answer 1

Entropy has a positive "change (◇S= positive) and gibbs free energy has a negative (◇G = negative ) "value" for a feasible reaction....


The answer is ◇G always decrease

Answer 2

Gibbs free energy always decreases.

Step-by-step explanation:

Entropy always decreases. False. For a spontaneous reaction entropy always increases.

Temperature always increases. False. A reaction may be spontaneous at high or low temperatures.

Gibbs free energy always decreases. True. For a spontaneous reaction Gibb’s free energy always decreases. ΔG is < 0. Gibb's free energy equation is:

ΔG = ΔH -TΔS

Gibbs free energy always increases. False.
