For real gases, the relation between P,V and T is given by van der Waa – InterviewSolution

1.	For real gases, the relation between P,V and T is given by van der Waals equation, (P+an2V2)(V−nb)=nRT.For the gases (CH4,CO2,O2,H2), which gas will have:(i) highest value of a?(ii) lowest value of b?
Answer» For real gases, the relation between $P, V$ and $T$ is given by van der Waals equation, $(P + \frac{a n^{2}}{V^{2}}) (V - n b) = n R T$ . For the gases $(C H_{4}, C O_{2}, O_{2}, H_{2})$ , which gas will have: (i) highest value of $a$ ? (ii) lowest value of $b$ ?
