Hydrogen gas (a potential future fuel) can be formed by the reaction of methane with water according to the following equation:
CH₄(g)+H₃O(g)→CO(g)+3H₃(g)
In a particular reaction, 25.5 L of methane gas (measured at a pressure of 732 torr and a temperature of 25 ∘C) is mixed with 22.2 L of water vapor (measured at a pressure of 702 torr and a temperature of 125 ∘C). The reaction produces 26.6 L of hydrogen gas at STP. What is the percent yield of this reaction?
