For a certain reaction at 25.0°C,the value of K is 1.2 $\times$ 10^-³.At 50.0°C the value of K is 3.4 $\times$ 10^-¹.This means that the reaction is

Question

Quizplus · Accepted Answer

The increase in temperature causes an increase in the value of K, indicating that the reaction is endothermic. As temperature increases, an endothermic reaction absorbs more heat to maintain equilibrium. Therefore, the correct choice is B) endothermic.
