Topic 6- Equilibria

Question 1

What is a reversible reaction?

Answer 1

When you can go forward and backwards in a reaction.

Question 2

What happens when you increase concentration of H2 in this reaction?
3H2+N2-> 2NH3

Answer 2

Increasing the concentration of H2 will cause the equilibrium to the right to reduce the concentration. Therefore more NH3 is produced to combat this.

Question 3

What happens when you increase pressure in this reaction?
3H2(g)+N2(g)->2NH3(g)

Answer 3

Increasing the pressure, equilibrium will shift to the side with the fewest gas particles therefore pressure is reduces and therefore more NH3 gas particles are produced.

Question 4

What happens when you decrease the pressure in this reaction?
3H2(g)+N2(g)-> 2NH3(g)

Answer 4

Decreasing the pressure, equilibrium will shift to the side with most number of gas particles will this increase the pressure therefore more N2 and H2 are produced.

Question 5

What happens when you increase the temperature of this reaction?
3H2+N2->2NH3
Reminder
Exothermic is -
Endothermic is positive

Answer 5

Increasing the temp, equilibrium shifts in endothermic direction to reduce the temperature therefore more H2 and N2 produced.

Question 6

What happens when you reduce the temperature in this reaction?
3H2+N2-> 2NH3

Answer 6

Decreasing the temperature, equilibrium will shift exothermic to increase the temperature therefore more NH3 produced to combat this equilibrium change.
