The van't Hoff equation relates two equilibrium constants at two different temperatures.
Consider a reaction where K298 = 16.3 and ΔH0 = −116 kJ/mol. Which of the following statements is true?
a. The reverse reaction is favored at 298 K.
b. A decrease in temperature will cause the forward reaction to be favored more.
c. An increase in temperature will cause the forward reaction to be favored more.
d. The value of K would be larger at 398 K.
e. The reaction is endothermic.
Answer: b. A decrease in temperature will cause the forward reaction to be favored more.
