Question

The van der Waals coefficents of mnatomic argon gas are a=0.1345m⁶Pa/mol²and b=32.19 x 10⁶m/mol . What is the change in temprature ΔT when one mole of argon gas undergoes a Joule free expansion from 0.1 L to 10L ?

a. ΔT = -107k

b. ΔT = 107k

c. ΔT =54k

d. ΔT = -54k

Expert Solution

Step 1

Given:

Vander waal coefficient of monoatomic krypton gas

a= 0.1345 m⁶Pa/mol²

b= 32.19 x 10⁶ m³/mol

Initial Volume (V₁) = 0.1 L

Final Volume (V₂) = 10 L

moles = 1 mol

To Determine:

The change in temperature, ΔT, when krypton gas undergoes a Joule free expansion
