# At high temperature and low pressure , the Van der Waal's equation is reduced to

$(a)\;[P+\large\frac{a}{V^2}][V]=RT\qquad(b)\;PV = RT\qquad(c)\;P(V-b)=RT\qquad(d)\;[P+\large\frac{a}{V^2}][V-b] = RT$

Can you answer this question?

At low P and high temperature Gases show ideal nature and deviations are minimum.
Hence answer is (b)
