Effect of pressure change

The video discusses chemical equilibrium, focusing on the formation of methane in a closed container. It explains how removing weight from a piston affects pressure and equilibrium, leading to a backward reaction that restores balance by forming carbon monoxide and hydrogen gases.

What is the initial setup described for the methane formation reaction?

• A container with a constant pressure

• An open system with no boundaries

• A closed container with a piston

• An open container with a fixed volume

What happens to the pressure inside the container when the weight on the piston is removed?

• The pressure increases

• The pressure remains constant

• The pressure fluctuates

• The pressure decreases

How does the chemical reaction respond to a decrease in pressure?

• It accelerates without direction

• It stops completely

• It shifts towards the reactant side

• It shifts towards the product side

What is the result of the backward reaction in the restoration of equilibrium?

• Formation of methane and oxygen

• Formation of carbon monoxide and hydrogen

• Formation of nitrogen and hydrogen

• Formation of water and carbon dioxide

Why does the reaction proceed towards the reactant side during equilibrium restoration?

• To increase the number of moles

• To decrease the number of moles

• To maintain the same number of moles

• To eliminate all moles
