Which gas exhibits the most intermolecular interactions

Reference no: EM133546493

Question: In this problem, two separate samples of gas are to be assessed with respect to van der Waal's real gas behavior i.e. an examination of intermolecular cohesive forces occupying some of the energy in each system (affecting pressure) and the effect of the particle size on the free space for which gas particles to move (affecting volume).

One gas is N2 gas and one is O2 gas. Each is contained in a separate 50.0mL container and cooled to 120K. Assume n = 1.00 mol of each gas present.

a) What is the measured pressure (P) for the N2 gas? What is the actual pressure (P+???)?

b) What is the measured pressure (P) for the O2 gas? What is the actual pressure (P+???)?

c) Comparing data from parts (a) and (b), take the ratio of the two actual pressures and compare it to the ratio of the molar masses of the two gases and discuss your findings.

d) Which gas exhibits the most intermolecular interactions? Why?

e) (cont.) Based on the fraction of free space remaining in the two containers, which gas would you predict to be the largest? Does that correlate to what we know about the relative sizes of the particles?
