Module Six Part B: Discussion Question Bonus 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?)

 

This is bonus for you to research and derive an answer based on the kinetic molecular theory. Read carefully my answers to Part A and apply these assumptions to the logic of how a real gas would have less pressure than ideal and need a pressure correction factor.

 

This is not in our book!

 

 

 

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

 

This is bonus for you to research and derive an answer based on the kinetic molecular theory. Read carefully my answers to Part A and apply these assumptions to the logic of how a real gasís volume is actually less than the ideal gas volume.

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:

 

 

_760__mmHg or _760__torre=__1___atm = Bonus: _29.9 in_= _14.7 psi_= 101 kPa

 

 

__0_ oC†† =††† _273__K

 

Are the values for the Molar Gas Volume Constant:

 

1 mole CO2 =__22.4__L CO2@STP†††††††† 1 mole H2 =__22.4___L H2@STP

 

 

1 mole N2 =__22.4___L N2@STP†††††††††† 1 mole O2 =__22.4___L O2@STP
