Question

For one mole of a gas, the total kinetic
energy is equal to
1. 2/3T 2. 1/RT 3. RT 4. 3/2 RT​

Answer 1

Answer:

(4) 3/2 RT

Explanation:

From kinetic theory of gases

(1/3)mnc2 = PV

So, PV = (1/3) mnc2

= 2/3(1/2) mnc2

= 2/3 KE

KE = 3/2 PV

For 1mol of a gas PV = RT

So, KE =( 3/2) RT
