alleryIf dissolution of a solid in a liquid is endothermic (Δ_sol H > 0), the solubility will:
ARemain unchanged with temperature
BFirst increase, then decrease
CIncrease with rise in temperature
DDecrease with rise in temperature
Answer & Solution
Correct answer: C. Increase with rise in temperature
By Le Chatelier: heating an endothermic equilibrium shifts it forward
→ **solubility increases** with T. (Exothermic dissolution → solubility decreases with T.)
