Question

What is the average kinetic energy of a gas at 285 kelvin? (R = 8.314 J/K-mol)

Answer 1

the answer would be 3.55 x 10^3 j/mol

Answer 2

The average KE = 312 J/mol

Step-by-step explanation:

Given:

Temperature of the gas, T = 285 K

Gas constant, R = 8.314 J/K-mol

To determine:

The average kinetic energy of the gas

Step-by-step explanation:

Based on the kinetic theory of gases, the average kinetic energy is given as:

`KE = (3)/(2) RT\\`

In this case:

`KE = (3)/(2) *8.314\ J/K-mol * 285\ K = 312 J/mol`
