Equilibrium

Question 1

reaction quotient

Answer 1

quantified amounts of the reactants and products present in the reaction mixture over time

Question 2

reaction quotient equation

Answer 2

concentration of products raised to stoichiometric powers over concentrations of reactions raised to stoichiometric powers

Question 3

equilibrium

Answer 3

the reaction is going both ways - the rate at which reactants are being converted into products is the same as the products being converted back into reactants

Question 4

equilibrium constant

Answer 4

the quantified amount of the system at equilibrium where Qe=Kc

Question 5

when Q>K

Answer 5

products are converted back into reactants until equilibrium is reached
equation moves to the left

Question 6

when Q<Kq

Answer 6

reactants are converted into products until equilibrium is reached
equation moves to the right

Question 7

what is lyalls litany

Answer 7

products raised to stoichiometric powers
divided by reactants raised by theirs
pure liquids and solids do not appear

Question 8

what does the magnitude of equilibrium constant K mean

Answer 8

gives information about the extent of the reaction at equilibrium

Question 9

how do you quantify equilibria

Answer 9

1. set up ICE table with all given information
2. calculate the change of given information
3. use stoichiometry of equation to calculate the change of other concentrations
4. use Kc formula for equilibrium

Question 10

explain Le Chaterlier’s principle

Answer 10

“if a system at equilibrium is disturbed, it will move in such a way to counteract the disturbance and restore equilibrium”
