For a Van der Waals gas, the following equations hold. P = nRT/(V−nb) − a(n/V)2 dU = CV dT + a(n/V)2 dV For chlorine gas, CV,m = 25.6 J K−1 mol−1, a = 6.343 bar L2 mol−2, and b = 0.0542 L mol−1. Calculate q, w, ΔU, and ΔH, in joules, when one mole of chlorine gas is expanded isothermally and reversibly at 449 K from 7.0 L to 15.0 L.

Initially, the volume and pressure of 0.1 mol of methane gas are 2.90 L (b) and 1 atm, respectively. The gas is allowed to expand adiabatically and reversibly to a pressure of 0.1 atm. Assume that the gas behaves ideally and the value of Cp/Cv is 1.31. (i) What is the final temperature of the gas? (ii) Calculate q, w, AU and AH in joule () for the process. (ii)...

The following applies to questions 17-21. Consider 1.00 mol of an ideal gas (Cp -5/2 R) initially at 1.00 atm that undergoes an isobaric expansion from 12.2 L to 22.4L Calculate AT, 4, w, AU, and AH for the change. AT = __K The following applies to question 12-16. Consider 1.00 mol of an ideal gas (CV-3/2 R) occupying 22.4 L that undergoes an isochoric...

I was wondering if someone could help me with problems on my
test my teacher allows me to correct the wrong ones then give them
back for half credit. Along with the correct answer for each I’d
like to know why the answer I chose is wrong what is the correct
answer and why it is the correct answer. The marked red problems
are the incorrect problems.
