A 25.0-L reaction vessel containing a mixture of CO₂ and excess F₂ is set up at 125 °C and 3.50 atm of pressure. According to the equation CO₂(g) + 4 F₂(g) → CF₄(g) + 2 OF₂(g), a spark ignites CO₂, resulting in its complete combustion. The temperature returns to 125 °C after the reaction, and the pressure of the mixture of product gases (CF₄, OF₂, and unreacted F₂) is found to be 2.85 atm. What are the partial pressures of the individual gases in the product mixture?
