Question 1

what is dynamic equilibrium

Answer 1

the forwards and backwards reactions which result in unchanged concentrations

Question 2

what happens when reversible reactions are left in sealed containers

Answer 2

dynamic equilibrium

Question 3

what can the position of equilibrium be shifted by

Answer 3

amounts of reactants or products, gas pressure, temperature

Question 4

what is le chateliers principle

Answer 4

the equilibrium shifts to counteract any change imposed on it

Question 5

what is equilibrium

Answer 5

the balance of reactants and products

Question 6

why do catalysts have no affect on the position of an equilibrium

Answer 6

as it increases the the both forward and backward reactions

Question 7

explain the dehydration/hydration of copper sulfate

Answer 7

heat copper sulfate crystals from blue to white as they lose water, add water to anhydrous copper sulphate white to blue as it absorbs the water
