Question

When pressure is increased over the system $ice\rightleftharpoons water$, what will happen ?

• A. More water will form
• B. More ice will form
• C. There will be no effect over equilibrium
• D. Water will decompose in H₂ and O₂

Answer 1

The correct option is A More water will form

$\underset{morevolume}{Ice}\rightleftharpoons \underset{lessvolume}{Water}$

Remember, ice is less dense than water! Using ideas from Le Chatelier's Principle: on increasing the pressure, equilibrium shifts forward.
