Hydrogen gas (a potential future fuel) can be formed by the reaction of methane with water according to the following equation: CH4(g)+H2O(g)?CO(g)+3H2(g) In a particular reaction, 26.0L of methane gas (measured at a pressure of 734torr and a temperature of 25 ?C) is mixed with 23.0L of water vapor (measured at a pressure of 704torr and a temperature of 125 ?C). The reaction produces 26.8L of hydrogen gas measured at STP. find the persent yield
