The video tutorial explains an experiment involving a piston-fitted chamber and inert gas. It focuses on a catalytic methanation reaction at constant volume and temperature. The addition of helium gas increases molecular collisions and total pressure but does not affect the partial pressures of individual gases, maintaining chemical equilibrium. The conclusion is that adding inert gas does not alter the equilibrium state.
