Question

At constant temperature, the pressure is directly proportional to the concentration of the gas.

(a) true

(b) false

This question was addressed to me at a job interview.

This key question is from Homogeneous Equilibria in section Equilibrium of Chemistry – Class 11

Answer 1

The correct choice is (a) true

To explain I would say: We have P = CRT e where p is pressure, R is a universal constant and T is the temperature, we derive the equation from the ideal gas equation PV=nRT. So from P = CRT, we can say that at a constant temperature the pressure is directly proportional to the concentration of the gas.
