 # In formula P = (nRT)/(v - b) e-a/RTV. Find dimensions of a and b where P = pressure, n = no. of moles, T = temperature, V = volume and R = Universal Gas constant.

P is pressure in N/m2 dimensional formula is : ML-1T-2

n is dimension less

dimesnion of temperature represented by the Greek letter theta is q

a/RTV shld be dimension less whihc means a has dimesnions same as RTV

dimesnion of a is :ML5T-2

b has dimensions same as volume i.e, m3 or L3

so, dimesnion of a is :ML5T-2

dimesnion of b is : L3
