A mixture of H2(g), O2 (g), and 2.0 ml of H2O(l) is present in a 0.500 L rigid container at 25oC. The number of moles of H2 and the number of moles of O2 are equal. The total pressure is 1146 mmHg. The equilibrium vapor pressure of pure water at 25oC is 24 mmHg. The mixture is sparked, and H2 and O2 react to produce water until one reactant is completely consumed.
(a) Identify the reactant remaining and calculate the number of moles of the reactant remaining.
(b) Calculate the total pressure in the container at the conclusion of the reaction if the final temperature is 90oC. The equilibrium vapor pressure of water at 90°C is 526 mmHg.
(c) Calculate the number of moles of water present as vapor in the container at 90oC
