Question

The vander wall's equation for a gas in(P+a÷v square)(V-b)=nrt where p,v,r,t,n are pressure ,volume,universal gas constant,absolute temperature and number of mole of gas.A and B are constants then the dimensional formula of b and dimensional formula of b÷a

Answer 1

Answer:

Explanation: as b is in substraction with Pressure and only quantities with same dimensional formula can be added or subtracted > therefore

Pressure = b

Force / area = b

M L T^-2 / L^2 = b

( M L^-1 T^-2 ) = b
