Methods for Van Der Waals Equation Calculator

Step 1:

Firstly, if you want to solve a problem you need to read the problem carefully than list all the values that are given in the problem.

Step 2:

Apply the van der Waals equation formula, and then substitute all the values to get all the equal values.

(P+an2/V2) (V-nb)=nRT

Step 3:

Explain whether the given answer is in proper units or not.

Some of the problems on Van der Waals equation

Calculate the temperature CO2 at the pressure 100bar and volume 3.317 X 10-4 m3/mol that can be used by a van der Waals equation. The van der Waals constants are 0.364 Nm4/mol2 and 4.267 X 10-5 m3/mol.

Step 1:

Given data

P = 100 bar = 10000000 Pascal

V = 3.317 × 10-4 m3/mol

R = 8.314

a = 0.364 N m4/mol2

b = 4.267 × 10-5

Step 2 : 

T = (10000000+(0.364×12)/(3 .317×10-4))×(3.317×10-4-1(4.267×10-5))/(1×8.314 )

T = 463 K

Step 3:

The temperature is given in Kelvin.


The temperature of CO2 is 463 K.
