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:
A process which is unfavorable with respect to enthalpy, but favorable with respect to entropy
a. could occur at low temperatures, but not a higher temperatures.
b. could occur at high temperatures, but not a lower temperatures.
c. could not occur regardless of temperatures
d. could occur at any temperatures
