What rules are there for pressure's effect on equilibrium?
An increase in pressure favours a decrease in volume, a decrease in temperature favours an increase in volume
1 of 7
Give an example of an experiment used in reversible reactions and give the formula (balanced!)?
Hydrated copper sulphate (blue) ---> anhydrous copper sulphate (white) + steam : CuSO45H2O --> CuSO4 + 5H2O
2 of 7
What is the test for water?
Hydrated copper sulfate --> Anhydrous copper sulfate + steam (if water is added it will turn blue, hence it being the test)
3 of 7
When does pressure affect a reaction?
GASEOUS reactions that have a change in volume!
4 of 7
Why do catalysts have no effect on equilibrium?
They speed up --> and
5 of 7
What rules are there for temperature on equilibrium?
Endothermic reactions are are favoured by a high temperature (heat change of +35 kj) and Exothermic reactions are favoured by a low temperature (heat change of -92 kj).
6 of 7
What other factors apply to reversible reactions and what effect do they have on equilibria?
Catalysts = increase (ONLY if no. mols aren't equal on both sides)
