write the equation and corresponding condition for reaction between nitrogen and hydrogen
Answers
Explanation:
N2+H2======2NH3
Temperature is about 200 to 400 celcius
Answer:
Hydrogen gas, H2, reacts with nitrogen gas, N2, to form ammonia gas, NH 3, according to the equation 3H2 (g) + N2 (g) → 2NH3 (g)
The reaction is reversible and the production of ammonia is exothermic.
Some notes on the conditions
The catalyst
The catalyst is actually slightly more complicated than pure iron. It has potassium hydroxide added to it as a promoter - a substance that increases its efficiency.
The pressure
The pressure varies from one manufacturing plant to another, 8but is always high. You can't go far wrong in an exam quoting 200 atmospheres.
Recycling
At each pass of the gases through the reactor, only about 15% of the nitrogen and hydrogen converts to ammonia. By continual recycling of the unreacted nitrogen and hydrogen, the overall conversion is about 98%.
