Equilibria

Question 1

dynamic

Answer 1

both forward and backward reactions are occurring simultaneously

Question 2

features of Dynamic Equilibrium

Answer 2

1. Forward and backward reactions are occurring at
   equal rates.
2. The concentrations of reactants and products stays constant

Question 3

Le Chatelier’s principle

Answer 3

tates that if an external condition is changed the equilibrium will shift to oppose the change (and try to reverse it)

Question 4

Effect of Temperature on equilibrium

Answer 4

If temperature is increased the equilibrium will shift to oppose this and move in the endothermic direction to try to reduce the temperature by absorbing heat.

Question 5

Effect of Pressure on equilibrium

Answer 5

Increasing pressure will cause the equilibrium to shift towards the side with fewer moles of gas to oppose the change and thereby reduce the pressure.

Question 6

Effect of Catalysts on Equilibrium

Answer 6

-has no effect on the position of equilibrium, but it will speed up the rate at which the
equilibrium is achieved.
-does not effect the position of equilibrium because it speeds up the rates of the forward and backward reactions by the same amount.
