equilibrium constant

Question 1

general reaction of for Kc

Answer 1

aA + bB ↔️ cC + dD

Question 2

general formula

Answer 2

kc = [C]^c [D]^d
——————
[B]^b [A]^a

Question 3

Kc =

Answer 3

[products]
—————-
[reactants]

Question 4

what happens when conc of products is greater than reactants

Answer 4

equilibrium lies to right

Question 5

what happens when conc of reactant is greater than products

Answer 5

equilibrium lies to left

Question 6

what happens when changing temperature

Answer 6

changes value of equilibrium constant

Question 7

exothermic

Answer 7

increasing temp
shifts equilibrium to left
value of Kc decreases

Question 8

endothermic

Answer 8

increasing temp
shifts equilibrium to right
value of Kc increases

Question 9

what is the only factor that affects equilibrium constant

Answer 9

ONLY TEMPERATURE
e.g conc is changed = Kc stays constant (ratio of products to reactants is restored to oppose the change & Kc value remains same)
catalysts = doesn’t change position of equilibrium/yield/value of Kc
