Challenge Problems
Push your limits with challenges.
Question 1
For a combustion reaction, the equilibrium concentrations of CO and CO2 were measured to be 0.5 and 0.2 moles per liter respectively. If the total pressure is 2 atm, calculate the mole fractions of each gas.
π‘ Hint: Use the total concentrations to find total moles before calculating mole fractions.
Question 2
Describe the steps you would take to iteratively solve for mole fractions in a system where Kp equals 0.8, and you have initial concentrations.
π‘ Hint: Consider how each mole fraction will push or pull the others during iteration.
