Ch 5C & D

Question 1

Le Chatelier’s principle describes the

Answer 1

behaviour of dynamic equilibrium systems
when they are disturbed.

Question 2

Le Chatelier’s principle states that

Answer 2

when a system in dynamic equilibrium is
subjected to a change, the system will adjust itself to partially oppose the effect of the change

Question 3

Addition of reactants

Answer 3

Equilibrium favours the forward reaction and shifts to the right to partially oppose the increase in concentration of
the reactants.

Question 4

Removal of reactants

Answer 4

Equilibrium favours the reverse reaction and shifts to the left to partially oppose the decrease in concentration of
the reactants.

Question 5

Addition of products

Answer 5

Equilibrium favours the reverse reaction and shifts to the left to partially oppose the increase in concentration
of products.

Question 6

Removal of products

Answer 6

Equilibrium favours the forward reaction and shifts to the right to partially oppose the decrease in concentration
of products.

Question 7

decreased volume causes reaction to

Answer 7

decrease in volume = increase in pressure
so reaction will shift to the side which produces less moles of gas

Question 8

effects of dilution on reaction

Answer 8

favours the shift that creates most number of particles

Question 9

in exothermic reactions increase in temp causes reaction to shift to the ______ and _____ K value

Answer 9

left, decreases

Question 10

in endothermic reactions increase in temp causes reaction to shift to the ______ and _____ K value

Answer 10

right, increases

Question 11

Compromise conditions 

Answer 11

conditions that may not always give the greatest yield of product, but are the most economically viable when it comes to balancing factors like
cost and rate of reaction

Question 12

Decarbonisation t

Answer 12

he process of reducing or eliminating carbon dioxide and other greenhouse gas emissions from industrial processes
