We’re being asked to determine which of the given statements is correct for a reaction given the sign of its ΔH and ΔS.
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 certain process has ∆H° < 0, ∆S° > 0, and ∆G° < 0. The values of ∆H° and ∆S° do not depend on the temperature. Which of the following is a correct conclusion about this process?
A) It is non-spontaneous at all T.
B) It is spontaneous at all T.
C) It is spontaneous at low T.
D) It is spontaneous at high T.
