Question

Which of the three gases will have the highest average kinetic energy at a given temperature

Answer 1

This is an incomplete question, here is a complete question.

Which of the three gases will have the highest average kinetic energy at a given temperature?

A) HBr

B) NO₂

C) C₂H₆

Answer : All three gases will have the same average kinetic energy at a given temperature.

Explanation :

The formula for average kinetic energy is:

$K.E=\frac{3}{2}kT$

where,

K.E = average kinetic energy

k = Boltzmann’s constant

T = temperature

As we know that, average kinetic energy depends only on the temperature.

As the temperature of the all three gases are same. So, the all three gases will have the same average kinetic energy.
