Question

One mole of O2 expands adiabatically against constant pressure of 1 atm until the pressure balances. Initial temperature and volume are 200 °C and 200 liter respectively. (i) Explain whether the process is reversible or not? ​

Answer 1

Answer:

One mole of O2 expands adiabatically against constant pressure of 1 atm until the

pressure balances. Initial temperature and volume are 200°C and 20 liter respectively.

I. Explain whether the process is reversible or not?

II. Calculate final temperature, work done and entropy change.

III. Will the quantities differ if, n moles of O2 were taken? Also give the reasons.

Assume ideal behavior.
