Module 6 SamplePretest

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 gas’s volume is actually less than the ideal gas volume.

This is not in our book!

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
