CHM 2045C Module Six Sample Exam

Module Six Part B: Discussion Question 5 points

In the Real Gas Equation: (P + an²/V²) (V - nb) = n RT a pressure correction factor was added. Why? (What assumptions of the kinetic theory breakdown under extreme conditions of temperature and pressure?)

Also a volume correction factor was subtracted. Why? (What assumptions of the KMT breakdown under extreme conditions?)

Module Six-Part C Standard Conditions/Molar Volume 5 points

State standard conditions (STP) in three units of pressure (the last is your choice) and ^oC and K temperatures:

_____mmHg or ______torre= ______atm = _____ ______

_____ ^oC = ______K

Are the values for the Molar Gas Volume Constant:

1 mole _CO2 =________L _CO2@STP 1 mole _H2 =________L _H2@STP

1 mole _N2 =________L _N2@STP 1 mole _O2 =________L _O2@STP
