Q. The equation of state of some gases can be expressed as Vander wal equation i.e. (P +a/v2)(V – b) = RT Where P is the pressure, V is the volume, T is the absolute temperature and a, b, R are constants. The dimensions of ‘a’ are:

  1. [M1L1T-1]
  2. [M1L-5T1]
  3. [M2L5T-1]
  4. [M1L5T-2]

Answer: [M1L5T-2]
