Question

For the reaction, H\(_2\)(g) + I\(_2\)(g) \( \rightleftharpoons \) 2HI(g), \( K_p \) = 0, what happens if the pressure on ice is increased at a constant temperature?

• A. Water to vaporize
• B. Water to freeze
• C. Increases
• D. No change

Hint:

When pressure is increased, the equilibrium will shift towards the side with fewer gas molecules, leading to the freezing of water.

Answer 1

The Correct Option is B

Step 1: Le Chatelier's Principle. According to Le Chatelier's principle, when the pressure is increased on ice at constant temperature, the equilibrium will shift to the side with fewer molecules of gas, which is the solid phase.
Step 2: Conclusion. Thus, the water will freeze.
