The units of van der Waals’ constants a, b respectively, are
View answer and explanation
Correct option: C
L2 atm  mol−2  and  mol−1  L{\mathrm{L}^2}\,\mathrm{atm\;mo}{\mathrm{l}^{ - 2}}\mathrm{\;and\;mo}{\mathrm{l}^{ - 1}}\mathrm{\;L}
Option C (L2 atm  mol−2  and  mol−1  L{\mathrm{L}^2}\,\mathrm{atm\;mo}{\mathrm{l}^{ - 2}}\mathrm{\;and\;mo}{\mathrm{l}^{ - 1}}\mathrm{\;L}) is correct because it represents the correct units derived from the van der Waals equation.
