Equilibria Flashcards
Describe the reversible reaction of the dehydration of hydrated copper(II) sulphate
If you add water to copper sulphate, you can make hydrated copper sulphate (blue).
If you remove water from hydrated copper sulphate, you can make copper sulphate (white).
Describe the reversible reaction of the effect of heat on ammonium chloride
When heated, ammonium chloride splits into hydrogen chloride and ammonia.
Hydrogen chloride and ammonia can be reacted to make ammonium chloride.
What is dynamic equilibrium?
Dynamic equilibrium is when a reversible reaction is happening both ways at the same time, at the same rate
What happens when you move the equilibrium to the right and left?
If you move the equilibrium, you change the rate of reaction
If the equilibrium moves to the right, you have more products (the reactants are reacting faster)
If the equilibrium moves to the left, you have more reactants (the products are reacting faster)
What happens if you increase and decrease the pressure?
If you increase the pressure: the equilibrium will move to the side with least molecules
If you decrease the pressure: the equilibrium will move to the side with the most molecules
What happens if you increase the temperature?
One reaction will be endothermic and the other will be exothermic.
The reaction that is endothermic will have their products increased as the reaction is trying to use up the extra heat, by putting the energy into making bonds.
