Le Chatelier

Question 1

What is Le Chateliers principle

Answer 1

Le Chateliers principle is that when there is a disturbance in a system it will readjust to reach equilibrium

Question 2

What is the effect of a shift in concentration on an equilibrium reaction?

Answer 2

If a higher concentration of a product is achieved, then the equilibrium shifts to the left (towards reactants)
should a lower concentration of products be achieved, the equilibrium shifts to the right (towards products).

Question 3

What is the effect of a shift in temperature on a system

Answer 3

An increase in temperature causes the system to shift to favour the endothermic change
A decrease in temperature causes the system to shift to favour the exothermic reaction

Question 4

What is the effect of inert gases on a system

Answer 4

Inert gases have no effect on the system as long as temperature and pressure remain the same

Question 5

What is the effect of a catalyst on a system

Answer 5

There is no effect on the equilibrium except it is reached faster

Question 6

What is the effect of a shift in volume on an equilibrium reaction?

Answer 6

Should the volume increase, the pressure will decrease. this causes a shift towards the side with the greatest number of moles of gas.
Should the volume decrease, the pressure will increase. This causes a shit towards the side with the smallest number of moles of gas.
