Reversible reactions

Question 1

What is a reversible reaction?

Answer 1

One where the products of the reaction can react with each other and convert back into the original reactants. It can go both ways.

Question 2

Dynamic equilibrium

Answer 2

1) This happens in a closed system.

2) Equilibrium means that the concentration of reactants and products will reach a certain balance and stay there.

Question 3

What is dynamic equilibrium?

Answer 3

A state at which reactions are still taking place in both directions but the overall effect is nil. The reactions cancel each other out because they are both occurring at exactly the same rate.

Question 4

How does temperature impact the position of equilibrium?

Answer 4

1) Increasing temperature will cause the endothermic reaction to increase to use up the extra heat.
2) Decreasing temperature will cause the exothermic reaction to increase to give out more heat.

Question 5

How does pressure impact the position of equilibrium?

Answer 5

1) Raising the pressure will encourage the reaction which produces fewer moles of gas.
2) Lowering the pressure will encourage the reaction which produces more moles of gas.

Question 6

How does adding a catalyst impact the position of equilibrium?

Answer 6

No effect
