🤓 Based on our data, we think this question is relevant for Professor Mamiya's class at TXSTATE.
Consider a reaction that has a positive ΔH and positive ΔS. Which of the following statements is TRUE?
a. the reaction will be spontaneous at high temps
b. reaction will be spontaneous at all temps.
c. reaction will be nonspontaneous at all temps.
d. reaction will be nonspontaneous at high temps.
e. not possible to determine without more information
We’re being asked to determine which of the given statements is true 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:
