1. Initially at 300 K and 10 atm pressure, 1 mol of a gas is allowed to expand adiabatically against a constant pressure of 4 atm until equilibrium is achieved. Assume the gas to be ideal with Cp,m = 28.58 + 1.76 x 10-2 T (The units of T are K and the units of Cp,m are J K-' mol-l.) Compute the final temperature and AH for this process.

1. Initially at 300 K and 10 atm pressure, 1 mol of a gas is allowed to expand adiabatically
against a constant pressure of 4 atm until equilibrium is achieved. Assume the gas to be ideal
with
Cp.m= 28.58 + 1.76 x 10-2 T
(The units of T are K and the units of Cp,m are J K- mol-!.) Compute the final temperature
and AH for this process.
