Question

find the dimensions of a and b in Vander waal 's equation (P+a/v2) (v-b)=RT​

Answer 1

Answer:

Vander Wall’s equation is given as,

$\: (p + \frac{a}{ {v}^{2} } )(v - b) = rt$

The dimension of a is given as,

$a = p {v}^{2}$

[ ML^-1 T^-2] [ L^3] ^2

[ ML^5T^-2]

The dimension of b is given as,

b=V

= [L ^3]

Thus, the dimension of a is [ML5 T −2 ] and the dimension of b is [L3].
