Question

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
A. `(P+(a)/(V^(2)))V=RT`
B. `P(V-b)=RT`
C. `PV=RT`
D. `(P+(a)/(V^(2)))(V-b)=RT`

Answer 1

At high pressure `V gt gt b`.
Hence, `(P+(a)/(V^(2)))V=RT`
