Equilbrium

Question 1

What is a reversible reaction?

Answer 1

• A reaction that can take place both forwards and backwards
• Reactants can turn into products
• Products can turn into reactants
• Rate of forward and backward reaction can be different

Question 2

What does it mean when a reaction is at eqilibrium?

Answer 2

• The rate of the forward and backward reaction is the same
• Concentration of reactants and products stays constant
• Reaction is still happening, concentration stays the same

Question 3

What does the position of equlibrium tell us?

Answer 3

• The concentration of the side that equilbirium is on is higher
• E.G: if equilibrium lies on the right, then at equilibrium the concentration of products is higher than the concentration of reactants

Question 4

What is required for equilibrium to be reached?

Answer 4

• Reaction must be done in a closed system so no reactants / products can escape

Question 5

What is true about reversible reactions and change in energy?

Answer 5

• One of the reaction will always be endothermice and the other will be exothermic
• If forwards reaction is exothermic, the backwards reaction is endothermic
