A quantity of .20 mole of carbon dioxide was heated to a certain temperature with an excess of graphite in a closed container until the following equilibrium was reached:
C(s) + CO2 (g) ----------> 2 CO (g)
<----------
Under these conditions, the average molar mass of the gases was 35g/mol.
a) Calculate the mole fractions of CO and CO2. (Hint: the average molar mass is the sum of the products of the mole fraction of each gas and its molar mass.)
Xco=_____________
Xco2=____________
b) What is the Kp if the total pressure is 15 atm?
Kp=______________
