Question

The following figures illustrate the initial state and equilibrium state of the reaction X₂(g) ⇌ 2 X(g).

Determine whether the reaction is spontaneous or nonspontaneous. What are the signs (+, −, or 0) of ΔH, ΔS, and ΔG when the reaction proceeds from its initial state to the equilibrium state?

Accepted Answer

The reaction is spontaneous at high temperature.
ΔH > 0, (+)
ΔS > 0, (+)
ΔG < 0, (−)

Answer

The reaction is nonspontaneous at all temperatures.
ΔH > 0, (+)
ΔS < 0, (−)
ΔG > 0, (+)

Answer

The reaction is spontaneous at low temperature.
ΔH < 0, (−)
ΔS < 0, (−)
ΔG < 0, (−)

Answer

The reaction is nonspontaneous at high temperature.
ΔH < 0, (−)
ΔS < 0, (−)
ΔG > 0, (+)
