At 298 ~K , assuming ideal behaviour, the average kinetic energy of a deuterium molecule is

Options

  1. Atwo times that of a hydrogen molecule
  2. Bfour times that of a hydrogen molecule
  3. Chalf of that of a hydrogen molecule
  4. Dsame as that of a hydrogen molecule

Correct answer

D. same as that of a hydrogen molecule

Step-by-step solution

( K . E .)_ average = 3 2 kT i.e., average kinetic energy depends only on temperature.
