WebFeb 27, 2024 · The constraints on the fraction of chemicals, such as CO 2, methane, NO x, and other gaseous emissions, from thermochemical reactions are the main contributors to global climate change. Carbon dioxide is considered the greenhouse gas with the highest contribution to global climate change [ 21, 24, 25 ]. WebA two-step chain reaction ensues in which the halogen atom abstracts a hydrogen atom from a methane molecule, resulting in the formation of a hydrogen halide molecule and a methyl radical ( CH3• ). The methyl radical then reacts with a molecule of the halogen to form a molecule of the halomethane, with a new halogen atom as byproduct. [24]
