Question

At what temperature will hydrogen molecules will have the same ke per mol

Answer 1

Answer:

At 280 K, hydrogen gas molecule will have same kinetic energy as that of the nitrogen gas molecule.

Explanation:

Kinetic Energy of gas molecule by the equation:

where,

K = Average kinetic energy

R = Gas constant

T = Temperature of the system

= Avogadro's number

Kinetic Energy of nitrogen gas molecule at 280 K:

..[1]

Kinetic Energy of hydrogen gas molecule at T':

[1] = [2]

Kinetic Energy of nitrogen gas molecule :

T' = 280 K
