Question

What kind of reaction occurs when the entropy change of an endothermic reaction is negative?

Answer 1

reaction is nonspontaneous under standard conditions at all temperatures.

Step-by-step explanation:

took the test.

Answer 2

Answer is: reaction is nonspontaneous under standard conditions at all temperatures.
Gibbs free energy (G) determines if reaction will proceed spontaneously.
ΔG = ΔH - T·ΔS.
ΔG - changes in Gibbs free energy.
ΔH - changes in enthalpy.
ΔS - changes in entropy.
T is temperature in Kelvins.
When ΔS < 0 (negative entropy change) and ΔH > 0 (endothermic reaction), the process is never spontaneous (ΔG> 0).
