Question

According to le-Chatelier 's principle, adding heat to a solid and liquid in equilibrium will cause the :

• A. Amount of solid to decrease
• B. Amount of liquid to decrease
• C. Temperature to rise
• D. Temperature to fall

Answer 1

The correct option is A Amount of solid to decrease

As the temperature is increased, solubility of solid in liquid increases and hence equilibrium shifts to the right and hence the amount of solid decreases.
