Equilibrium - Coggle Diagram
Equilibrium
-
Dynamic Equilibrium
- D: reversible reaction
- amount of each reactant/product remains constant
- rate of the forward reaction EQUAL to rate of backwards reaction
-
-
-
position of equilibrium and
product yield can be altered by:
- changing concentration
- changing pressure (gaseous)
- changing temperature
Changing
Concentration
- increasing concentration of reactant
- MOVES EQ to RIGHT
- to oppose change made to system
- increasing YIELD OF PRODUCT
- adding acid = increase conc H+ ions
- MOVES EQ to RIGHT
- (to use up H+ ions)
Changing
Pressure
- increase in pressure
- position of EQ to move to side with fewer gas molecules - to RIGHT (lower mole ratio)
- increasing yield of product
Changing
Temperature
-
-
- increase in temperature
- EQ to MOVE to LEFT = COLD
- decrease product yield
-
Haber Process
-
conditions
-
-
iron catalyst (solid)
(speed up reaction + allow EQ to be reached faster)
HETEROGENEOUS CATALYST
(D: in different phase from reactants)
with conditions ^^^ = only 20-25%
N + H converted to NH3, liquified + removed
(unreacted gases retained + reused)
