Chemical Thermodynamics Question 339

Question: One mole of an ideal gas at 300 K is expanded isothermally from an initial volume of 1 litre to 10 litres. The AE for this process is (R=2calmol1k1)

Options:

A) 163.7 cal

B) zero

C) 1381.1 cal

D) 9 lit atm

Show Answer

Answer:

Correct Answer: B

Solution:

For a finite change ΔE=CvΔT . For an isothermal process ΔT=0 . Hence ΔE=0
