The change of enthalpy of this reaction is equal to -481.06 kJ. [3] The heat provided by the main reaction serves as a catalyst for other side reactions. CH 4 + H 2 O → CO + 3 H 2 2 CH 4 + 3 O 2 → 2 CO + 4 H 2 O 4 NH 3 + 3 O 2 → 2 N 2 + 6 H 2 O. These side reactions can be minimized by only short exposures to the catalyst of the order of ...

Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The 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 [1]) in the presence of a nickel catalyst.
The methanation reactions are classified as exothermic and their energy of formations are listed. [1] There is disagreement on whether the CO 2 methanation occurs by first associatively adsorbing an adatom hydrogen and forming oxygen intermediates before hydrogenation or dissociating and forming a carbonyl before being hydrogenated. [3]

Reactant: the numbers of each of the elements on the reactants side of the reaction equation. Product: the number of each element on the product side of the reaction equation. The layout should eventually look like this, for a balanced reaction of baking soda and vinegar: HC 2 H 3 O 2 + NaHCO 3 → NaC 2 H 3 O 2 + H 2 CO 3
The third reaction, known as radical consumption layer, where most of the heat is released, and the first reaction, also known as fuel consumption layer, occur in a narrow region at the flame. The fourth reaction is the hydrogen oxidation layer, whose thickness is much larger than the former two layers.
The Fischer–Tropsch process involves a series of chemical reactions that produce a variety of hydrocarbons, ideally having the formula (C n H 2n+2). The more useful reactions produce alkanes as follows: [7] (2n + 1) H 2 + n CO → C n H 2n+2 + n H 2 O. where n is typically 10–20. The formation of methane (n = 1) is unwanted.
