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
