Reversible equilibria Flashcards
When does a reversible reaction occur
The rpdocuts can turn intothe reactants
Ammonium chlordie is made by
Ammonia and hydrogen chloride
What isbhydrated
It has water
What is anhydrodrous
Without water
What is thermal decomposition
Using heat to break it down
What are is the product of a hydrates coper sulphate
Anhydrous copper sulfate
What is the symbol equation for hydrated copper sulfate
Cuso45h20
What is the word equation for the Haber pricess
Nitrogen plus hydrogen equals ammonia
Symbol equation for the Haber process
N2 plus 3h2 equals 2nh3
What is the symbol for ammonia
Nh3
What are the conditons for the Haber porcess
450
200 atmospheric pressure
Iron catalyse
Why is iron catalyse used in the Haber process
As it increases the rate of reaction . It doesn’t change the direction of the reversable reaction or the position of the quilibium
What is dynamic ewuilibrium
No overall change in the products or reactants even though the reactions are ongoing . It takes placed in a closed system
What is chatiloers priniciple
A system will adjust itself to mimize any change
What will happen if you increase the temperature in the Haber process
The equilibrium will shift in the endo direction and the equilibrium decreases the temperature and it will produce more reactant
What will happen if you decrease the temperature in the Haber process
Equilibrium shifts in the exothermic direction and the produces more product
What will happen if you decrease the concentration of ammonia
Equilibrium shifts to the product to produce more and minimize change
What will happen if you increase the ammonia in the Haber process
Equilibrium shifts to the reactants and reduces the amount of ammonia
If you increase the pressure in the Haber process
Shifts to the side with the fewest gas molecules to minimise change
By decreasing the pressure it will
Shift to side with more gas molecules
How do you maximise productivity in the Haber process
The ammonia is cooled , liquidised and then removes as it is a product . This causes the equilibrium to produce more product more ammonia
What do plants need for growth
Sunlight , space , mineral ions
What is needed by plants
Fertilisers
What are the three fertilisers needed for growth
Nitrogen , phosphorus and potassium are all
Why are fertilisers soulabke
They need to be soluble as they need to be absorbed by the roots along with water
How is nitric acid formed
Ammonia + oxygen -(equals) nitric acid + water
What is the symbol for nitric acud
Hno3
What is put together to make ammonia nitrate
Ammonia + nitric acid
What is the symbol for nitric acid
Hno3
How do you produce ammonium sulpahte . The preparation in a lab
Use titration to neutralise then crystallisation and this will be completed in a batch process
How do you produce ammonia sulphate industrial prepartrations
Sulphuric acid is made in raw materials like , sulphur air and water
Ammonia is made within using water and natural gas
Hydrogen and air
And these will react to make ammonia sulphate
The symbol equation for sulphuric acid
H2s04
