Chapter 19 Equilibria

Question 1

What do different values of K represent ?

Answer 1

• K = 1 equilibrium position is halfway
• K = 100 equilibrium position favours the products
• K = 1x10^-2 equilibrium position favours the reactants

Question 2

What condition causes the value of K to change ?

Answer 2

• at a given temperature K does NOT change
• K can only change when temperature changes
• pressure or concentration cannot change the value of K

Question 3

What happens to the K value when there is an increase in temperature (forwards is exothermic) ?

Answer 3

K value decreases with increasing temperature, raising temperature decreases equilibrium yield of product
