Question

The gas equation for n moles of a real gas is: $(P + \frac{n ^{2} a}{V ^{2}}) (V - nb) = nRT$ where P is the pressure, V is the volume, T is the absolute temperature, R is the molar gas constant and $a, b$ are arbitrary constants. Which of the following have the same dimensions as those of PV?

Options:

Answer:

A, B

Solution:

$PV + \frac{a}{V} - Pb - \frac{ab}{V ^{2}} = nRT$ dimension of $PV =$ dimension nRT .
