Web3 okt. 2024 · Chemical properties of methane are similar to properties of other representatives of a number of alkanes. So it is characterized by the following chemical reactions: 1. conversion of methane to synthesis gas: CH4 + H2O → CO + 3H2 (kat = Ni/Al2O3 at to = 800-900 OS or without catalyst at to = 1400-1600 OS). Web6.87. Methanogenesis Some methanogenic bacteria use acetic acid (CH3COOH) and hydrogen to make methane. Write a balanced chemical reaction for the synthesis of methane and water from hydrogen and acetic acid and calculate the standard enthalpy of the reaction by using the appropriate enthalpies of formation from Appendix 4. 6.88 Milit
