Question

Please answer it. I beg youuuuuu

Answer 1

Answer:

1.

Since an/VRT is a power, it is dimensionless and a has the same dimensions as VRT/n.

These dimensions are volume × energy /amount^2 expressed in m^3J mol^-2.

b has the same dimensions as V/n, which are volume/amount expressed in m3 mol^-1

2.

The term an^2/T^ 1/2V( V + nb) has the same dimensions as p, so a has the same

dimensions as T^1/2Vpn^-2

The SI units are K^1/2 m^6 Pa mol^-2

b has the same dimensions as V/n, which are volume/amount expressed in m3 mol^-1
