FREE Expert Solution

We’re being asked to determine when would a process which is unfavorable with respect to enthalpy, but favorable with respect to entropy occur.


The statements given describe the spontaneity of the reaction at different temperatures

Recall that when ΔH and ΔS are given, we can determine the spontaneity of the reaction based on their signs

We can use the Punnett square shown below:
