equilibria

Question 1

how is dynamic equilibrium reached (from start to end)

Answer 1

At start of reaction forward reaction is fast + backward reaction is slow

after the start, the backward(reverse) reaction speeds up while the forward reaction slows down

the rate of forward reaction becomes same as rate of backwards reaction

Question 2

state le chateliers principle

Answer 2

the position of equilibrium will shift to oppose a change made to it

Question 3

which 3 factors effect the position of equilibrium

Answer 3

conc
pressure
temp

Question 4

CO + H20 —->CO2 + H2
<——

What willl happen if the conc of CO increased

Answer 4

Equilibrium shifts to the right to oppose the increase in CO conc

yield of CO2 + H2 increases

Question 5

CO + H20 = CO2 +H2

What if the conc of CO decreases

Answer 5

equilibrium will shift to the left to oppose the decrease in CO conc

Yield of CO + H20 increases

Question 6

if the pressure is increases , which side will the equilibrium shift to

Answer 6

the equilibrium will shift to the side which fewer moles

Question 7

if the pressure is decreased, which side will the equilibrium shift to

Answer 7

shift to the side w the more moles

Question 8

cost on conditions

Answer 8

increase pressure means more expensive
increase temp means more cost
presence of yield reduces overall cost
