13A.2 Flashcards
what is partial pressure (of a gas in a mixture of gasses)
the pressure the gas would exert if it alone occupied the volume of the mixture
the total pressure of a system is equal to
the sums of all the gas’s partial pressure in an equation
how can we define an equation for the Kp using partial pressure?

what is the equation to calculate the partial pressure of gas in a mixture of other gases
Partial pressure =the mole fraction of the gas x total pressure
what’s the equation for the mole fraction of a gas
number of moles of the gas / total number of mole of gases
what will happen to solids that are in equilibrium with gases when writing the Kp
they will not be included in the expression of Kp
what does this equation (Kp = (pCO2)0 tell us
for a particular temperature, the pressure of CO2 in the equilibrium mixture is constant regardless of any solid mass it was with, in the equilibrium(this can be proved experimentally)
what is saturated water vapor
the partial pressure of water (pH2O(g)) in eq with its liquid (this proves that water boils at 100c)
what will happen to liquids that are in equilibrium with gases when writing the Kp
they are not represented on expression for Kp
what is the pH2O(g) = to at 373K and how does this show water boils at 100c
the PH2O is 1 atm, and the boiling point of a liquid is defined at the temp at which the saturated vapor pressure = the external pressure which in the case is 1 atm = 373K = 100C
