O KINETICS AND EQUILIBRIUM Calculating the reaction rate of one reactant from that of another Esther v The reform reaction between steam and gaseous methane (CH) produces "synthesis gas," a mixture of carbon monoxide gas and dihydrogen gas. Synthesis gas is one of the most widely used industrial chemicals, and is the major industrial source of hydrogen. Suppose a chemical engineer studying a new catalyst for the reform reaction finds that 204. liters per second of methane are consumed when the reaction is run at 240. °C and the methane is supplied at 0.33 atm. Calculate the rate at which dihydrogen is being produced. Give your answer in kilograms per second.
