Temperature and K for an exothermic reaction
For an exothermic reaction at equilibrium, raising the temperature will:
Answer B: explanation for every choice
A
This is the response of an endothermic reaction.
B
Correct. In an exothermic reaction, heat acts like a product. Adding heat shifts the reaction backward, and K decreases.
C
Temperature is the one variable that changes K.
D
The shift happens because K itself changes.
TakeawayExothermic: heating lowers K. Endothermic: heating raises K.
