We’re being asked to determine the signs of ΔH and ΔS if ΔG is positive at all 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:
If ΔG is positive at all temperatures, then the sign of ΔS is ______ and ΔH has a ______ sign.
A. positive, negative
B. negative, positive
C. small, zero
D. large, zero
E. large, small
