Which one of the following statements is not correct? a. An increase in temperature causes an increase in gas pressure because the average force of molecules colliding with the walls of the container increases. b. An increase in temperature causes an increase in gas pressure because the frequency of molecules colliding with the walls of the container increases. c.

Question 1 (a) Use the ideal gas equation to calculate the pressure (in atm) of 2.40 mol of krypton (Kr) at 455 K in a 4.50 L vessel. (b) In a 16.3 L vessel, the pressure of 2.40 mol of Kr at 455 K is 5.50 atm when calculated using the ideal gas equation and 5.40 atm when calculated using the van der waals equation of state (Note: a=5.121 and b = 0.0106). Why is the percent difference in...

Question 1 (1 point) 1.50 Oxygen PV 1.ok Ideal gas 0.0 0 200 400 600 800 1000 Pressure (atm) 1. Above is a graph of one mole oxygen and an "ideal gas". The ratio of PV/T is plotted as a function of gas pressure. Why is the line that represents oxygen different from that of the "ideal gas"? Oxygen deviates from an ideal gas because it is diatomic Real gas molecules have a small but measurable intermolecular attraction Oxygen is...
