Self Test 9.17A

Postby Selena_Wong_1I » Thu Jan 26, 2017 8:56 am

Determine delta S,delta Ssurr, and delta Stot for (a) the reversible, isothermal expansion and (b) the isothermal free expansion of 1.00 mol of ideal gas molecules from 10.00 atm and 0.200 L to 1.00 atm and 2.00 L at 298 K.

Why can we disregard the pressures ( 10 atm and 1 atm) when solving this problem?

If Delta S = q/T, and the process is reversible, q = -w = nRT ln (V2/V1), what does this say about Delta S? And what is the relationship between q and w in this system?
