Two moles on an idea gas is expanded isothermally and reversibly at 300 K form 1L to 10L. The enthalpy change in KJ is

Options

  1. A11.4 kJ
  2. B4.8 kJ
  3. C-11.4 kJ
  4. DZero kJ

Correct answer

D. Zero kJ

Step-by-step solution

The enthalpy change at constant pressure is given as: Δ H = C p Δ T For isothermal expansion Δ T = 0 ∴ Δ H = 0
