For a moles of gas ,Van der Weals equation is `(p = (a)/(V^(-2))) (V - b) = nRT`ltbr. Find the dimensions of a `a and b `, where `p = pressure` of gas` ,V = volume` of gas and` T = temperature of gas` .

Text Solution

Verified by Experts

The correct Answer is:
A, B
`[b] = [V] = [L^(2)]`
` ([a])/([V]^(2)) = [p] = [ML^(-1) T^(-2)]`
`rArr [aa] = [ML^(2)T^(-2)]`
