Methane when burnt in the presence of metallic catalyst (Cu), at high temperature (400°C) and pressure (200atm), which of the following is the ultimate product?

Explanation

Option C is correct.When methane is burnt in the presence of a metallic catalyst (Cu), at high temperature (400°C) and pressure (200 atm), the ultimate products are carbon dioxide and water. The reaction can be represented as:CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)The metallic catalyst, high temperature, and pressure facilitate the reaction by providing favorable conditions for the combustion process. The combustion of methane involves the oxidation of carbon and hydrogen, resulting in the formation of carbon dioxide and water. Other options like Methanol, Ethanol, and Methanoic acid are not the correct products of this specific combustion reaction.
