Equilibrium

Question 1

What is a reversible reaction?

Answer 1

A reaction in which reactants can change into products and products can change back into reactants.

Question 2

What is dynamic equilibrium?

Answer 2

The rates of the forward reaction and reverse reaction are equal and the amounts of reactants and products remain constant.

Question 3

State Le Chateliers principle:

Answer 3

If a change is made to the conditions of a system at equilibrium, then the position of equilibrium moves to oppose that change in conditions.

Question 4

What will and increase in temperature do to the position of equilibrium?

Answer 4

Change it in the direction of the endothermic reaction.

Question 5

What will a decrease in temperature do to the position of equilibrium?

Answer 5

Change it in the direction of the exothermic reaction.

Question 6

What does an increase in pressure do to the position of equilibrium?

Answer 6

Moves the position of equilibrium in the direction of fewer gas moles.

Question 7

What does a decrease in pressure do to the position of equilibrium?

Answer 7

Moves the equilibrium in the direction of greater gas moles.

Question 8

What does and increase in concentration do to the position of equilibrium?

Answer 8

Moves the position of equilibrium in the direction of the forward reaction.

Question 9

If position of equilibrium moves to the right,

Answer 9

Yield increases

Question 10

If position of equilibrium moves to the left,

Answer 10

Yield decreases
