Chemical Equilibrium Concepts

The video tutorial covers the factors affecting chemical equilibrium, including concentration, temperature, pressure, and volume. It provides instructions for group activities to explore these concepts and discusses the impact of each factor on the direction of equilibrium shifts. The tutorial also includes examples and explanations to help students understand the principles of chemical equilibrium.

Who is the chemist mentioned in the introduction that contributed to the concept of equilibrium?

• Henry Louis

• Albert Einstein

• Isaac Newton

• Marie Curie

What happens to the equilibrium when the concentration of a reactant is increased?

• It becomes unstable

• It remains unchanged

• It shifts towards the products

• It shifts towards the reactants

If the concentration of a product is decreased, in which direction will the equilibrium shift?

• It will oscillate

• It will not shift

• Towards the products

• Towards the reactants

How does an increase in temperature affect an endothermic reaction's equilibrium?

• Shifts towards the reactants

• Causes a reaction to stop

• Shifts towards the products

• No effect

What is the effect of decreasing temperature on an exothermic reaction's equilibrium?

• Causes a reaction to stop

• No effect

• Shifts towards the products

• Shifts towards the reactants

When pressure is increased, towards which side does the equilibrium shift?

• Towards the side with more moles

• Towards the side with fewer moles

• No shift occurs

• It becomes unstable

What happens to the equilibrium when the volume is decreased?

• Shifts towards the side with more moles

• It becomes unstable

• Shifts towards the side with fewer moles

• No shift occurs

How does a catalyst affect the equilibrium of a reaction?

• Shifts towards the reactants

• Shifts towards the products

• Speeds up the attainment of equilibrium

• Slows down the reaction

What is the role of a catalyst in a chemical reaction?

• Stops the reaction

• Increases the reaction rate

• Decreases the reaction rate

• Shifts the equilibrium

Which factor does not affect the position of equilibrium?

• Concentration

• Temperature

• Pressure

• Catalyst
