CI - Kc Equilibrium Constant

Question 1

how do you write a Kc expression?

Answer 1

products
Kc = —————–
reactants

Question 2

effects of changing pressure on Kc:

Answer 2

increasing pressure shifts the eqm to the side of the reaction with the least moles of gas

this will reduce the pressure returning to normal

more product will be obtained

Question 3

effects of changing temp on Kc:

Answer 3

increasing temp favours the endothermic side of the reaction (the products)

Question 4

effects of catalyst on Kc:

Answer 4

they do not affect the position of equilibrium constant they just increase the speed at which the reaction takes place
