WebSince CO and H2 is a 2:1 mol ratio from the balanced equation, we know we'll have to use twice as much H2 as we do CO, or 25.4 mols of H2. If we had 32.2 mols of H2 initially to work with, then the leftover H2 is the differernce between the mols of H2 we initially had and the mols used up in the reaction, or 32.2 - 25.4 = 6.8 mols of excess H2. WebThe Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa ) in the presence of a nickel catalyst.It was discovered by the French chemists Paul Sabatier and Jean-Baptiste Senderens in 1897.
