Q

What is equilibrium?

A

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.

Q

What is Châtelier’s principle?

A

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

Q

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

A

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

Q

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

A

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

Q

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

A

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

Q

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

A

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