equilibrium

Question 1

le chatliers principle

Answer 1

if a reaction at equilibrium is subjected to change in pressure, temp, conc, the position of equilibrium will move to counteract the change

Question 2

adding catalyst

Answer 2

catalyst have no effect on position of equilibrium

will speed up backward and forward reactions equally

Question 3

changing pressure

Answer 3

if we increase pressure the equilibrium shifts to reduce the pressure

the side with less gas particles

Question 4

changing conc.

Answer 4

if we increase/ decrease the conc. of reactant OR product equilibrium will shift and try reduce the conc.

side with less/ more moles

Question 5

changing temperature

Answer 5

increase in temperature equilibrium will shift to reduce temp

shifts in the endothermic direction

Question 6

equilibrium constant (kc)

Answer 6

[C][D][A][B]

Question 7

reversible reactions

Answer 7

reactions that go back and forth

Question 8

forward reaction

Answer 8

reactants are used up quickly but slows as conc. drops

Question 9

backward reaction

Answer 9

reactants are reformed slowly but speeds when conc. increases

Question 10

dynamic equilibrium

Answer 10

forward rate and backwards rate are equal
