What is the key difference between irreversible and reversible reactions?

• Irreversible reactions proceed in one direction only, while reversible reactions can proceed in both forward and reverse directions.

• Irreversible reactions can be easily reversed

• Reversible reactions only occur in living organisms

• Irreversible reactions always reach equilibrium

Can irreversible reactions be undone?

• Yes

• Only on weekends

• No

• Sometimes

Give an example of an irreversible reaction.

• Photosynthesis in plants

• Rusting of iron

• Combustion of wood

• Boiling water

How can you identify if a reaction is reversible?

• Observing if the products can react to form the original reactants under suitable conditions.

• Measuring the temperature of the reaction

• Checking the color change of the reactants

• Counting the number of products formed

Are reversible reactions common in nature?

• Yes

• No

• Rarely

• Sometimes

Explain the concept of dynamic equilibrium in reversible reactions.

• Dynamic equilibrium is achieved in reversible reactions when the rates of the forward and reverse reactions are equal, leading to a constant concentration of reactants and products.

• Dynamic equilibrium occurs when only the forward reaction is happening

• Dynamic equilibrium leads to a depletion of reactants

• Dynamic equilibrium results in a constant increase in product concentration

Why is it important to understand the difference between irreversible and reversible reactions?

• To calculate the molecular weight of the products

• To predict the weather conditions during the reaction

• It is important to understand the difference between irreversible and reversible reactions to predict reaction direction, determine equilibrium state, and design efficient chemical processes.

• To determine the color of the reactants

What factors can influence the reversibility of a reaction?

• Phase of the reactants

• Temperature, pressure, concentration, catalysts, nature of reactants and products

• Color of the reactants

• Time of day

Discuss the implications of irreversible reactions in industrial processes.

• Irreversible reactions always lead to 100% product yield

• Irreversible reactions do not require careful process design

• Irreversible reactions have no impact on industrial processes

• Irreversible reactions in industrial processes have implications on efficiency, product yield, and process design.

How do catalysts affect the reversibility of reactions?

• Catalysts speed up the reversibility of reactions

• Catalysts do not affect the reversibility of reactions.

• Catalysts slow down reversible reactions

• Catalysts make reactions irreversible
