10.5 The Equilibrium constant Kc - Part 1

Question 1

When does a dynamic equilibrium exist

Answer 1

When the rate of the forward reaction is equal to the rate of the reverse reaction

Question 2

How is the exact position of equilibrium calculated

Answer 2

Using the equilibrium law

Question 3

What does the equilibrium law define

Answer 3

The equilibrium constant (Kc) in terms of concentrations

Question 4

What do you need to know in order to calculate an equilibrium constant

Answer 4

The equilibrium concentrations of the reactants and products

Question 5

What does a Kc value of 1 indicate

Answer 5

A position of equilibrium that is halfway between reactants and products

Question 6

What does a Kc value >1 indicate

Answer 6

A position of equilibrium that is towards the products

Question 7

What does a Kc value <1 indicate

Answer 7

A position of equilibrium that is towards the reactants

Question 8

The larger the value of Kc, the…

Answer 8

…further the position of equilibrium lies to the right-hand side and the greater the concentrations of the products compared to the reactants
