Cog has a constant pressure molar heat capacity of 2914 j, Ask an Expert

Academics

CO(g) has a constant pressure molar heat capacity of 29.14 J mol -1 K -1. A system consists of 5.00 moles of CO(g), initially at 285 K and 0.750 bar. The surroundings are at 285 K. The gas may be assumed to be ideal. Calculate the entropy change for the system, the surroundings, and the universe when the gas increases in volume by a factor of four in each of the following processes:

(a) an adiabatic, reversible expansion

(b) an isothermal, reversible expansion
