Solution
Correct Answer:
Increase in temperature
The effect of temperature on solubility is governed by Le Chatelier's Principle.
- For a majority of solid solutes, the dissolution process is endothermic (Heat is absorbed; ΔHsoln>0).
- Increasing the temperature provides energy to the system, causing the equilibrium to shift in the forward direction (more dissolving) to consume the excess heat.
- Therefore, solubility generally increases with an increase in temperature for such substances. Pressure has negligible effect on the solubility of solids.
This easy difficulty chemistry question is from the chapter solutions, covering the topic of solubility. It appeared in the 2025 exam.
