Question

In the reduced form of the van der Waals equation, (P_r + (3)/(V_r^2))(3V_r - 1) = 8T_r, where P_r = P/P_c, V_r = V_m/V_c and T_r = T/T_c. Which statements are correct?

Accepted Answer

The equation contains no constants characteristic of any particular gas

Accepted Answer

At the critical point P_r = V_r = T_r = 1 satisfies the equation

Accepted Answer

Two gases at the same P_r and T_r have the same V_r

Accepted Answer

The equation implies Z_c is the same for all van der Waals gases
