The reform reaction between steam and gaseous methane (CH_4), 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 612 liters per second of methane are consumed when the reaction is run at 213 degree C and 0.94 atm. Calculate the rate at which dihydrogen is being produced. Give your answer in kilograms per second. Be sure your answer has the significant digits.
