Question

Balance nitrogen reacts with hydrogen in the presence of iron as a catalyst at 200 atmospheric pressure and 600 degree temperature ,and the product obtained is ammonia

Answer 1

Answer:

N2 + 3H2 ------- 2NH3. ( ∆H = _ 46.1 kj/mol ).

This is known as habers process.

Explanation:

1) The forward reaction is exothermic and it is

accompanied with decrease in no of moles.

2) optimum conditions :

a) Increase in concentration of N2(or) NH3(or) both and decrease in concentration of NH3 gives good yeild of NH3.

b) Temperature : 725-775K.

c) Pressure : 200 atm.

d) catalyst : Iron oxide mixed with little amounts of K2O and AL2O3 .

e) promoter : Molybdenum (MO).

Answer 2

Answer:

na2+3h2------2nah3
