Le Chateliers Principle

Question 1

what happens when you add more concentration

Answer 1

the reaction will favor the opposite side

Question 2

what happens when you remove a reactant

Answer 2

it will go towards whichever is removed

Question 3

what happens when you increase volume and decrease pressure

Answer 3

it moves to which ever side has MORE moles of GAS

Question 4

what happens when you decrease volume but increase pressure

Answer 4

when volume is decreased it favours the side with fewer moles of gas

Question 5

increasing temp in an endothermic reaction

co + energy = 2co + o2

Answer 5

shift to the right (away from reaction)

——–>

Question 6

decreasing temp of an endothermic reaction

Co + energy = 2co + o2

Answer 6

shifts to the left (towards it)

Question 7

increasing temp of an exothermic reaction

so2 + o2 = so3 + energy

Answer 7

shift to the left

Question 8

decreasing temperature of an exothermic reaction

so2 + o2 = 2so + energy

Answer 8

shift to the right ———–>

Question 9

what will not shift an equilibrium

Answer 9

adding solids or liquids

catalysts

Question 10

pressure will have no effect when

Answer 10

both sides are equal

Question 11

increasing temp of an endothermic reaction

Answer 11

right ——–>

Question 12

increasing temp of an exothermic reaction

Answer 12

left

Question 13

decreasing temp of an endothermic reaction

Answer 13

left

Question 14

decreasing temp of an exothermic reaction

Answer 14

—–> right towards the heat source
