The Equilibrium Constant, Kc

Question 1

The equilibrium expression links the equilibrium constant, Kc, to the concentrations of reactants and products at equilibrium taking the stoichiometry of the equation into account
So, for a given reaction:

aA + bB ⇌ cC + dD

Question 2

the Kc is defined as

Answer 2

kc = C[D]power of d) over
AB

Question 3

What is the meaning of Kc

Answer 3

products over reactants

with number of molecules of each substance as a power

Question 4

units of [A] [B] AND [C] [D]

Answer 4

[A] [B] is mol dm-3 of reactants

[C] [D] is mol dm-3 of products

Question 5

What state is ignored in equilibrium expressions

Answer 5

solids

Question 6

The Kc of a reaction is specific and only changes if the

Answer 6

temperature of the reaction changes
