Question

the Van der Waals equation for a gas is (p+a/v square)(v-b)=RT. Determine the dimensions of a & b.

Answer 1

a is the vanderwal's gas constant
p'=p+na
b is the vanderwl's volume constant

Answer 2

Hey mate
your answer is here

unit of p = unit of a/v^2

so,
unit of a = p×v^2
[a] = ML^5T^-2

and
unit of b = unit of volume

so,

[b] = L^3

Hope this help you
