` (P + ( a ) / ( V^ 2)) ( V - b ) ` = RT is the real gas equation. Find the dimensions of a & b.

Text Solution

Verified by Experts

(i) `[P] = [ ( a ) /(V^ 2 )] `
` therefore [ a ] = [ PV^ 2 ] = [M^ 1 L^ ( -1) T ( -2) L^6] `
i.e, ` [a] = [M ^ 1 L ^5 T^( -2) ] `
(ii) `[V] = [b] `
i.e, `[b] = [M^(0) L ^3T^0] `
