The values of critical presssure, critical volume and critical temperature for hydrogen gas are 12.97 bar, 0.065 L `"mol"^(-1)` and 33.2 K. Calculate the compressibility factor.

Text Solution

Verified by Experts

Compressibillity factor (z) for one mole of gas is given interms of critical presssure `(P_(C))`. Critical volume `(V_(C))` and critical temperature `(T_(C))` as
`z = (P_(c)V_(c))/(RT_(c)) = (12.97 xx 0.065)/(0.083 xx 33.2)`
Compressibility factor ` = 0.306`

At a particular temperature and pressure for a real gas Van der Waal's equation can be written as: (P + a/(V^(2)m)) (V_(m) -b) =RT where Vm is molar volume of gas. This is cubic equation in the variable Vm and therefore for any single value of P & T there should be 3 values of Vm. Which are shown in graph as Q, M and L. As temperature is made to increase at a certain higher temperature the three values of Vm becomes identical. The temperature, pressure & molar volume at point X are called Tc, Pc & Vc for real gas. The compressibility factor in terms of Pc, Vc and T is called Zc. The value of critical compressibility factor Zc is approximately
