Question 1

1.

Increasing the pressure in a system at equilibrium causes .....

The forward reaction rate to increase

The concentration of the gases to increase

The reverse reaction rate to increase

All of these options are correct

Question 2

2.

Consider the Haber reaction system at equilibrium.

What happens when pressure is decreased?

The reverse reaction speeds up

The yield of ammonia increases

The reverse reaction is favoured.

Nitrogen gets used up more quickly

Question 3

3.

Consider the following system in equilibrium.

Pressure is increased by reducing the volume of the container.
What does NOT happen as a result?

Both reaction rates increase

All the gases increase in concentration

The forward reaction is favoured

All of these things happen as a result

Question 4

4.

Consider the following graph.
What is NOT a possible cause of the disturbance?

Increase in temperature

Decrease in volume

Increase in pressure

Increase in concentration of reactants

Question 5

5.

Consider the following system at equilibrium which experienced a disturbance.

What was the disturbance?

An increase in temperature

A increase in concentration of the system

An increase in pressure of the system

An increase in the volume of the system
