In (P+(a)/(V^(2)))(V-b)=RT equation the, a,b will be ..... Where P= Pressure V= Volume and T= Temperature .

At higher pressure van der Waals' equation becomes, PV=R , PV=RT+a/V , PV=RT-a/V , PV=RT+Pb

Using van der Waals equation (P+(a)/(V^(2)))(V-b)=RT , answer the following questions: At high pressure, the van der Waals equation gets reduced to
