Equilibria

Question 1

Define Dynamic Equilibrium

Answer 1

When the forward and backward reactions occur at a constant rate

Question 2

Define Le Chateliers Principal

Answer 2

When a system is subject to change it will alter to lessen the effect of the change

Question 3

What is the effect of increasing TEMPERATURE, on a reversible reaction

Answer 3

1. Favours the endothermic side
   2.heat and therefore energy is removed from the system

Question 4

What is the effect of increasing PRESSURE, on a reversible reaction

Answer 4

Favours the side with less mols

Question 5

What is the effect of increasing CONCENTRATION, on a reversible reaction

Answer 5

Favours the opposite side to which the concentration is increased on

Question 6

What is the effect of a catalyst on a reversible reaction

Answer 6

Catalysts have no effect as they effect forward and backward equally, it only speeds up the time until dynamic equilibrium is reached

Question 7

What is Kc

Answer 7

The Equilibrium constant

Question 8

What properties affect Kc

Answer 8

Only temperature
