Vanadium(v) Oxide
Enzymes (in yeast)
Iron
zeolite ZSM-5
Collision Theory
Increase in concentration
Increase in pressure
Increase in temperature
Chemical Equilibria
dynamic equation
reversible reaction
forward reaction
reverse reaction
Le Chatelier's principle
Changing the temperature
endothermic
exothermic
reducing the concentration
Changing the pressure
decrease pressure
increase pressure
Catalyst
not affect the position of equilibrium
condition used in Harbor Process
A pressure of 200 atmospheres
A catalyst of finely divided iron
An optimum temperature of 450 Celsius
Ammonia is condensed out of the reaction mixture
Nitrogen and hydrogen mixed in ratio of 3:1
remaining nitrogen and hydrogen is recycled
