Question

For an ideal gas at any given temperature and pressure, the ideal gas law is used to express ____

(a) Concentration of gas molecules

(b) Mobility of gas molecules

(c) Kinetic energy of gas molecules

(d) Potential energy of gas molecules

I had been asked this question by my school teacher while I was bunking the class.

The above asked question is from Liquid and Gas Phase Reactions in division Kinetics of Homogeneous Reactions of Chemical Reaction Engineering

Answer 1

Correct choice is (a) Concentration of gas molecules

Explanation: Ideal gas law is given as, PV = nRT,

Where, P – Pressure

T – Temperature

R – Universal gas constant

n – Number of gas moles

V – Volume

Concentration is the number of moles per unit volume = \(\frac{n}{V} = \frac{P}{RT}. \)
