The video tutorial explains the formation of methane from carbon monoxide and hydrogen through catalytic methanation. It details the chemical reaction involving 4 moles of reactants forming 2 moles of products. The impact of pressure on the concentration of reactants and products is discussed, highlighting the greater number of collisions on the reactant side. The video compares QC and KC values, explaining how pressure changes lead to partial reactions and affect the number of gaseous products. It concludes with the incompressibility of solids and liquids in equilibrium mixtures.
