Question

Calculate the pressure exerted by one mole of co2 gas at 273 k

Answer 1

According to van der Waals equation of state for 1 mole of a gas,

(P + a/V2)(V- b) = 0

Since, the volume occupied by CO2 molecules is negligible, b = 0.

(P+A/V^2)V=RT
P=RT/V^2-A/V^2
0.082×273/22.4-3.592/{(22.4)^2
0.9922atm
