Question
Kp, the equilibrium constant for a gas phase reaction, is calculated using these values instead of molarities. For 10 points each:
[10m] Name this measure of the concentration of a gas in a mixture. It is proportional, but not equal, to mole fraction.
ANSWER: partial pressure [prompt on pressure; prompt on P; prompt on P-sub-i]
[10e] The ratio between Kp and Kc is an integer power of this unit of molar energy. According to the ideal gas law, “PV equals n” times this term, usually abbreviated to two letters.
ANSWER: RT [or R times T; or the ideal gas constant times temperature; accept kT or the Boltzmann constant times temperature]
[10h] For non-ideal vapors, the partial pressures in Kp are also multiplied by this quantity. This quantity symbolized phi is the ratio between the pressures of an ideal gas and real gas that have the same chemical potential.
ANSWER: fugacity coefficient [reject “fugacity”; reject “activity coefficient”]
