ES - Chemical Equilibrium

Question 1

meaning of the term equilibrium:

Answer 1

state of balance where nothing changes what is

Question 2

what is dynamic equilibrium?

Answer 2

a forward and a reverse reaction are both happening and are equal to each other remaining constant

Question 3

what is le chataliers principle?

Answer 3

if a dynamic equilibrium is disturbed the position of equilibrium shifts to counteract the change to re-establish an equilibrium

Question 4

what happens during dynamic equilibrium?

Answer 4

conc of the products and reactants remain constant (NOT THE SAME)
forward and reverse reaction are both happening
rate of forward and reverse reaction are both equal to each other

Question 5

what is the equilibrium constant Kc?

Answer 5

Kc = [products] / [reactants]

Question 6

what is indicted if Kc is greater then 1?

Answer 6

there must be more products than reactants
top must have larger value then bottom
this means eqm lies to the right hand side

Question 7

what happens to Kc when theres a change in concentration?

Answer 7

system will change until eqm is reached again and it will always adjust to keen Kc constant as long as TEMP STAYS CONSTANT

Question 8

what happens to eqm when pressure increases?

Answer 8

eqm shifts to side with fewer mols of gas

Question 9

what happens to eqm when pressure decreases?

Answer 9

eqm shifts to side with the most mols of gas

Question 10

what happens to eqm when temp increases?

Answer 10

shifts eqm to side of endothermic reaction

Question 11

what happens to eqm when temp decrease?

Answer 11

eqm shifts in direction of the exothermic reaction
