Question

One mole of an ideal gas at 300 K is expanded isothermally from an initial volume of 1 litre to 10 litres. The ΔE for this process is: 

(R = 2 cal mol^–1 K^–1 )

a. 163.7 cal 

b. zero 

c. 1381.1 cal 

d. 9 lit atom

Answer 1

Correct option  (B) zero

Explanation:

For isothermal expansion of ideal gas, ΔE = 0
