MISSED THIS? Read Section 6.7 (Pages 235-238); Watch IWE 6.12. 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, 25.0 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 704 torr and a temperature of 125 °C). The reaction produces 26.4 L of hydrogen gas at STP. Part A What is the percent yield of the reaction? 15. ΑΣΦ Submit Provide Feedback Request Answer PARANG ? %
