Chemical Thermodynamics Question 187
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=2calmo{{l}^{-1}}{{k}^{-1}}) $
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 $ \Delta E=C_{v}\Delta T $ . For an isothermal process $ \Delta T=0 $ . Hence $ \Delta E=0 $
