Question

A vessel divided into 2 parts by a partition, contains 4 mol of nitrogen gas at 348.15K and 30 bar on one side and 2.5mol of argon gas at 130C and 20bar on the other. If the partition is removedand the gases mixes adiabatically, and comletely, what is the change in entropy? Homework Equations Assuming Nitrogen is an ideal gas with Cv = (5R/2) and argon to be an ideal gas with Cv=3R/2

Answer 1

Answer:

A vessel, divided into two parts by a partition, contains 4 mol of nitrogen gas at 75°C and 30 bar on one side and 2.5 mol of argon gas at 130°C and 20 bar on the other. ... Given that the gases mix adiabatically, means . Let be the final temperature of the mixture
