Dynamic Equillibrium

Question 1

What is a reversible reaction?

Answer 1

A reversible reaction is a reaction that occurs in both a forward and reverse direction.

Question 2

When does dynamic equilibrium occur?

Answer 2

Dynamic equilibrium occurs in a closed system when there is a reversible reaction

Question 3

What is equilibrium?

Answer 3

Equilibrium- the point in a reversible reaction where the forward and reverse rates of a reaction are equal. Therefore the amounts of products and reactants are equal.

Question 4

What is Châtelier’s principle?

Answer 4

Equilibrium will shift to reduce change. If conditions change the reaction will do everything it can to counteract the change.

Question 5

What happens to the position of equilibrium if pressure of a gas increases?

Answer 5

It shifts in the direction with fewer gas molecules and fewer molecules in the same space means lower pressure.

Question 6

What happens to the position of equilibrium when there is an increase in concentration?

Answer 6

It shifts in the direction that uses up the added substance and using up substances lowers concentration.

Question 7

What happens to the position of equilibrium when there is an increase in temperature?

Answer 7

It shifts in the direction that is endothermic as endothermic reactions lower the temperature.

Question 8

When happens to the position of equilibrium when using a catalyst?

Answer 8

It doesn’t change as catalysts speed up reactions but don’t affect direction.
