The average kinetic energy of molecules in a gas at temperature T is 1.5 kT. Find the temperature at which the average kinetic energy of the molecules of hydrogen equals the binding energy of its atoms. Will hydrogen remain in molecular from at this temperature? Take k = 8.62 × 10 –5 eV K –1 .

Question

Philoid · Accepted Answer

As we know Binding energy of a system is defined as the energy released when its constituents are brought from infinity to form the system.

So,

Binding energy

According to this question the binding energy is equal to the average kinetic energy of the molecules.

So,

No, it is not possible because according to question positive ion of hydrogen molecules exists which is practically impossible.

The average kinetic energy of molecules in a gas at temperature T is 1.5 kT. Find the temperature at which the average kinetic energy of the molecules of hydrogen equals the binding energy of its atoms. Will hydrogen remain in molecular from at this temperature? Take k = 8.62 × 10–5 eV K–1.
