🤓 Based on our data, we think this question is relevant for Professor Bruehl's class at CU.

Solution: Hydrogen gas (a potential future fuel) can be formed by the reaction of methane with water according to the equation:  CH4(g) + H2O(g) → CO(g) + 3 H2(g) In a particular reaction, 25.5 L of methane gas (measured at a pressure of 732 torr and a temperature of 25 °C) mixes with 22.8 L of water vapor (measured at a pressure of 702 torr and a temperature of 125 °C). The reaction produces 26.2 L of hydrogen gas at STP. What is the percent yield of the reaction?

Problem

Hydrogen gas (a potential future fuel) can be formed by the reaction of methane with water according to the equation: 

CH4(g) + H2O(g) → CO(g) + 3 H2(g)

In a particular reaction, 25.5 L of methane gas (measured at a pressure of 732 torr and a temperature of 25 °C) mixes with 22.8 L of water vapor (measured at a pressure of 702 torr and a temperature of 125 °C). The reaction produces 26.2 L of hydrogen gas at STP. What is the percent yield of the reaction?
