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.

Can you help me correcting this questions in the picture with the notes below please? Notes: In question 1a, the rate law is fine but should have partial pressures, not concentrations. In 1b, the units of the answer are incorrect; they should have "atm" in it. Hint: in the denominator of the calculation is atm^3.
Calculating the reaction rate of one Peactant from that of ano In the Haber reaction, patented by German chemist Fritz Haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. This reaction is now the first step taken to make most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 394. liters per second of dinitrogen are consumed when the reaction is run at 209. °C and the dinitrogen is supplied at 0.45 atm.
