Van Der Waals Coefficient-a

$a = 3 * "pc" * V_c ^2$

Enter a value for all fields

This equation computes the a-coefficient in the Van der Waals equation of state from the critical pressure, $p_c$ , and the critical molar volume, $V_c$ .

The Van der Waals equation is $p = (R*T)/(V_m-b) - a/V_m^2$ .
