Question 1

what is equilibrium

Answer 1

for a reversible reaction in a closed system, equilibrium is reached when the rate of the forwards reaction equals the rate of the backwards reaction.

Question 2

what happens in equilibrium

Answer 2

both reactions continue to happen, but the amount of reactants and products remain the same

Question 3

what is le chateliers principle

Answer 3

whenever you change the conditions in a system in equilibrium, the position of equilibrium shifts so it cancels out the change.

Question 4

what happens to the reaction when you increase the pressure

Answer 4

the position of equilibrium will shift to reduce pressure.

Question 5

what happens If the forward reaction produces more molecules of gas

Answer 5

an increase in pressure decreases the amount of product formed
a decrease in pressure will increase the amount of product formed

Question 6

what happens if the forwards reaction produces fewer molecules of gas

Answer 6

an increase in pressure increases the amount of product formed
a decrease in pressure decreases the amount of product formed

Question 7

what does increasing the temperature favour

Answer 7

favours the endothermic reaction
