Consider the combustion (burning) of methane, CH₄, in oxygen. CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l)
The heat of reaction at 77 degrees C and 1.00 atm is -885.5 kJ. What is the change in volume when 1.00 mol CH₄ reacts with 2.00 mol O₂? (You can ignore the volume of liquid water, which is insignificant compared with volumes of gases.) What is w for this change? Calculate ΔU for the change indicated by the chemical equation.
