We’re being asked to determine when is a reaction with a positive enthalpy spontaneous.
Recall that using ΔH and ΔS, we can determine the spontaneity of the reaction based on their signs.
We can use the Punnett square shown below:
When is a reaction with a positive enthalpy spontaneous?
a. when the temperature is high and the change in entropy is positive
b. when the temperature is low and the change in entropy is positive
c. when the temperature is high and the change in entropy is negative
d. when the temperature is low and the change in entropy is negative
e. when the product of the temperature and the change in entropy are negative
