Fertilisers Flashcards
1
Q
What one three of the elements needed for plant growth
A
Nitrogen phosphorous potassium
2
Q
Hater process formula…
A
Nitrogen + hydrogen = ammonia (reversible reaction)
N2 (g) + 3H2 (g) = 2NH3 (l)
3
Q
What is temp and pressure conditions In Haber process
A
Moderate temp ( reaction too slow at low temp, ammonia decomposes at high temp)
High pressure yields more ammonia
4
Q
What catalyst is used In Haber process?
A
Iron
5
Q
What is the role of a condenser in the Haber process?
A
Cools the reaction down, turning ammonia into a liquid which is easier extract
