Reversible Reactions

What is a reversible reaction?

The product molecules can react with each other or decompose to form reaction molecules again.

What is ammonia chloride broken into and what is the forward reaction?

Ammonia and hydrogen chloride, endothermic

What does hydrated copper sulfate turn in to?

Anhydrous copper sulfate and water.

What is equilibrium?

When the rate of the forward reaction equals the rate of the backwards reaction

When is equilibrium dynamic?

In a closed system.

What happens to concentration of reactants and products if there’s no changes.

They remain constant.

What is the haber process?

Nitrogen gas reacts with hydrogen to make ammonia.

What happens to the rate of reaction in the haber process as concentration decreases.

Rate of reaction decreases.

What happens to the rate of reaction in the haber process as concentration of ammonia increases?

Rate of backward reaction increases

What is Le Chatelier’s principle?

If a change occurs to a reaction in equilibrium the position of the equilibrium will move to counteract the change.

What happens if temperature of a reaction increased?

The position of the equilibrium moves in the endothermic direction to reduce the temperature.

What does it mean if forward reaction if favoured?

The equilibrium shifts to the right to form more product.

If concentration increases what happens to the equilibrium?

It shifts to the side where less product is produced until equilibrium is reached again.

If concentration decreases what happens to the equilibrium?

It shifts to the side where more product is produced until equilibrium is reached again.

If pressure increases what happens to the equilibrium?

It shifts to the side with less moles.

If pressure decreases what happens to the equilibrium?

It shifts to the side with more moles.

If temperature increases what happens to the equilibrium? (endothermic)

Relative quantity of products at equilibrium increases..

If temperature increases what happens to the equilibrium? (exothermic)

The relative quantity of products at equilibrium decreases .

If temperature decreases what happens to the equilibrium? (endothermic)

The relative quantity of products at equilibrium decreases.

If temperature decreases what happens to the equilibrium? (exothermic)

The relative quantity of products at equilibrium increases.

What happens if there’s the same number of moles on each side and pressure changes?

There is no change in equilibrium position,
