Question

In Vander wall’s equation

( P + a / V2

) ( V – b ) = RT

What are the dimensions of a and b? Here P is pressure, V is volume, T is temperature

and R is gas constant.​

Answer 1

Answer:

Vander Wall's Equation

Explanation:

Vander Wall's equation is given as,

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

= RT

The dimension of A is given as,

a = PV²

= [ML^-1 T ^-2] [L³]²

= [ML⁵T ^-2]

The dimension of B is given as,

a = V

= [L³]

Thus the dimension of a is [ML⁵T ^-2] and dimension of b is [L³]
