Unit 3 - The Harbor Process Flashcards
What will the equilibrium do if the temperature is decreased?
It will move to try to inscrease the temperature
In a reversible reaction, if the forwards reaction is exothermic, what is the backwards reacton?
Endothermic
In general, what temperatures are exothermic reactions favoured by?
Low temperatures
In general, what temperatures favour endothermic reactions?
high temperatures
What with the equilibrium do if the pressure is increased?
The equilibrium will move to try to decrease the pressure
In general what sort o reactions does high pressure favour?
Reactions with more molecules of reactant that product
In general, what reactions does low pressure favour?
Reactions with more molecules of product than reactants
What is the effect of a catayst on equilibrium?
It doesnt efect the position of equilibrium, but it means its reached quicker
In an endothermic reaction, what does increasing the temperature do?
increases the yield
In an exothermic reaction, what does decreasing the temperature do?
increases the yield
What is the harbor process used to make?
Ammonia, which is used to make fertilisers
What raw matericlas are used in the Harber process?
Hydrogen and Nitrogen
What ratio are nitrogen and hydrogen reacted at?
N 1:3 H
What pressure and temperature is the harbor process done at?
Pressure: 200 atmospheres
Temperature: 450°C
What are the main uses of ammonia?
In the household, it removes grease because it is a weak alkali
Industrially in making: Nitric acid and Fertilisers (eg ammonium nitrate)
