Equilibria /KP

Question 1

Define:
dynamic equilibrium,

Answer 1

rate of the forward reaction is equal to the reverse reaction
Concentrations of reactants and product remain constant

Question 2

essential condition for and equilibrium mixture

Answer 2

equilibrium occurs ion a closed system

Question 3

state le chatelier’s principle

Answer 3

system at equilibrium is disturbed the equilibrium moves in the direction that tends to reduce the disturbance

Question 4

forward reaction endothermic
what effect would increasing the temperature have on the position of equilibrium

Answer 4

shifts to right

Question 5

moles —> 2:4
AH: +240 KJ mol-1
what effect would increasing the pressure have on the position of equilibrium

Answer 5

shifts to left
more moles on right hand side

Question 6

Answer 6

no effecr

Question 7

what does Kc being greater or lesser than 1 suggest for the position of equilibrium

Answer 7

Greater than 1= over to the right
Lesser than 1+ over to the left
