Reaction of Thermal Decomposition of Methane (CH4)

The thermal decomposition of methane (CH4) refers to the reaction in which methane breaks down into its constituent elements, carbon (C) and hydrogen (H2), under the influence of heat. This reaction is an endothermic process, meaning it requires the input of energy to proceed.

The balanced chemical equation for the thermal decomposition of methane is as follows: CH4 → C + 2H2

The reaction can be initiated by heating methane to high temperatures, typically above 1000°C. At these elevated temperatures, the weak carbon-hydrogen bonds in methane are broken, resulting in the formation of carbon and hydrogen gas.

The thermal decomposition of methane is an important reaction in various industrial processes, such as the production of hydrogen gas and the synthesis of carbon nanotubes. It is also a significant contributor to the greenhouse effect and climate change, as methane is a potent greenhouse gas.

Reaction of Thermal Decomposition of Ethane (C2H6)

Similarly to methane, ethane (C2H6) can also undergo thermal decomposition under high temperatures. The reaction involves the breaking of the carbon-carbon and carbon-hydrogen bonds in ethane, resulting in the formation of carbon (C) and hydrogen gas (H2).

The balanced chemical equation for the thermal decomposition of ethane is as follows: C2H6 → 2C + 3H2

The thermal decomposition of ethane is typically carried out at temperatures above 900°C. At these temperatures, the energy input breaks the bonds in ethane, leading to the formation of carbon and hydrogen gas.

The reaction of thermal decomposition of ethane is important in various industrial processes, such as the production of acetylene gas and the synthesis of carbon fibers. It is also a source of carbon emissions and contributes to air pollution.
