At 27c Average Kinetic Energy Of One Mole Of Helium Chemistry Question

At 27⁰C average kinetic energy of one mole of helium gas can be given

Options

(a) 3741.30 J mol⁻¹
(b) 374.13 J mol⁻¹
(c) 1662.8 J mol⁻¹
(d) 166.28 J mol⁻¹

Correct Answer:

3741.30 J mol⁻¹

Explanation:

The average kinetic energy per mole does not depend on the nature of the gas but depends only on temperature. Average Kinetic energy per mole = 3 / 2 RT. given, T = 27⁰C = 273 + 27 = 300 K. R = 8.314 JK⁻¹ mol ⁻¹ ⇒ K.E = 3/2 x 8.314 x 300 = 3741.3 J mol ⁻¹.
