dynamic equalibrium

Question 1

what is a reversible reaction

Answer 1

• a reversible reaction is when the products can react with each other to produce the original reactants

Question 2

what is a closed system

Answer 2

• a closed system is where none of the products or reactants can escape

Question 3

what happens when a reaction reaches equilibriums

Answer 3

• both reactions are still happening
• the concentration balance and don’t change

Question 4

what is equalibrium

Answer 4

• when the forward reaction is going exactly at the same rate as the backward one in a closed system

Question 5

what are the three factors that can change the position of the equilibrium

Answer 5

• temperature
• pressure (only involving gasses)
• concentration

Question 6

what does it mean if a reaction lies to the right

Answer 6

• lesser concentration of reactants
• greater concentration of products

Question 7

what does it mean if a reaction lies to the left

Answer 7

• greater concentration of reactants
• lesser concentration of products

Question 8

what does Le Chatelier’s principle state

Answer 8

• Le Chatelier’s principle states that if there is a change in concentration pressure or temperature in a reversible reaction , the equilibrium will move to counteract that change

Question 9

what happens to the position of the equilibrium if you increase or decrease temperature

Answer 9

• if temperature is increased the equilibrium will move to the endothermic left reaction side to absorb extra heat
• if temperature is decreased the equilibrium shifts to the exothermic right side to produce more heat

Question 10

what happens to the position of the equilibrium if you increase or decrease pressure

Answer 10

• if you increase the pressure , the equilibrium will shift to the side with fewer moles of gas to reduce pressure
• if you decrease the pressure, the equilibrium will move to the side with more moles of gas to increase pressure

Question 11

what happens to the position of the equilibrium if you increase concentration

Answer 11

• if you increase the concentration of the reactants, the equilibrium will shift to the right to use up the reactants to make more products
• if you increase the concentration of the products, the equilibrium will shift to the left to use up the reactants to make more reactants

Question 12

what happens to the position of the equilibrium if you decrease concentration

Answer 12

• if you decrease the concentration of the reactants, the equilibrium will shift to the to use up the products to make more reactants
• if you decrease the concentration of the products, the equilibrium will shift to the left to use up the products to make more reactants
