So I'm super confused by this one question in EK 1001 chemistry, it's on page 21, question 217 if you wanna check it out.
The question states, according to the graph, which of the following would be true, if the ideal gas law, PV-nrt were used to calculate the volume of a sample of CH4 gas from measured variables at 200atm and 300K and again at 600 atm and 300k?
the answer is... the calculated volume would be greater than the real volume for 200 atm and less than real volume for the 600 atm sample..
The graph essentially shows at pressure on the x axis and (PV/RT) on the y axis. Ideally, the y axis should be at 1 all the time, but at 200 it is less than 1 and at 600 it is more than 1.
I though I had ideal gas down pat, but this question is killing me. Any help would be greatly appreciated!
