(a)
Interpretation:
The values for Van der Waals parameters a, b, and R from zc, Tc, Pc and Vc should be calculated.
Concept Introduction :
The Universal gas constant can be calculated from zc, Tc, Pc and Vc as follows:
Also, the constants a and b can be calculated as follows:
Here, R − universal gas constant
Vc − critical volume
Pc − critical pressure
Tc − critical temperature
(b)
Interpretation:
The Van der Waals parameters a and b should be calculated using the critical constants for water and correct value for R.
Concept Introduction :
The constants a and b can be calculated as follows:
Here, R − universal gas constant
Vc − critical volume
Pc − critical pressure
Tc − critical temperature
