At what temperature will the hydrogen molecules have the same kinetic ...
Explanation:

  • We know that the kinetic energy of a gas molecule is given by the formula:


K.E. = (3/2) kT


  • Here, k is the Boltzmann constant, T is the temperature in Kelvin and (3/2) is the degree of freedom of a gas molecule.

  • For diatomic molecules like hydrogen and nitrogen, the degree of freedom is 5 (3 translational and 2 rotational).

  • Now, we need to find the temperature at which hydrogen molecules have the same kinetic energy per mole as nitrogen molecules at 280 K.

  • Let us assume that the kinetic energy per mole of nitrogen molecules at 280 K is K.


K = (3/2) kTN


  • Similarly, the kinetic energy per mole of hydrogen molecules at the same temperature is:


(3/2) kTH


  • Now, we need to find the temperature at which both these kinetic energies are equal:


(3/2) kTN = (3/2) kTH

TH = TN


  • So, the temperature at which hydrogen molecules have the same kinetic energy per mole as nitrogen molecules at 280 K is 280 K.


Therefore, option A is the correct answer.
