MCQ

At equilibrium on increasing pressurre boiling point of $H_2O$

✓
Boiling point of water increases
B
Boiling point of water decreases
C
Boiling point of water remains unchanged
D
Nothing can be assumed

✓

Answer

Correct option: A.

Boiling point of water increases

a
The equilibrium reaction is $H _2 O ( l ) \rightleftharpoons H _2 O ( g )$, when pressure is applied, the equilibrium will shift to left as the value of $\Delta n$ is positive. Hence, for boiling to occur more temperature is required. So, it will increase the boiling point.
