Formula for van der Waals equation - Thermodynamics

Q.  The equation pv=RT is used for ideal gases. The right equation for real gases is van der Waals equation. What is the correct formula for the van der Waals equation?Where
(a/v2)= force of cohesion
b= coefficient related to volume of molecules
- Published on 20 Aug 15

a. (p+(a/v2)) (v + b) = RT
b. (p – (a/v2)) (v – b) = RT
c. (p + (a/v2)) (v – b) = RT
d. (p – (a/v2)) (v + b) = RT

ANSWER: (p + (a/v2)) (v – b) = RT
