Question

The scheme below shows various reactions starting with hydrogen and nitrogen .study it carefully and answer the question that follows.

1. Name the substances:
   1. T 
   2. U 
   3. A 
   4. Q 
   5. W 
   6. C 
2. Name the catalyst which could be used in:
   1. Step I 
   2. Step II 
3. Write equations for the reaction occurring in:
   1. Step I 
   2. Step II (two equations)
4. What property of ammonia gas is shown in its reaction with copper II oxide? 

Answer 1

1.  
   1. T - Nitrogen 
   2. U - Hydrogen 
   3. A - Ammonium Sulphate 
   4. Q - Nitrogen Gas 
   5. W - Copper 
   6. C - Oxygen gas 
2.  
   1. Step I - Iron  
   2. Step II - Platinum Rhodium 
3.   
   1. Step I 
      N2(g) + 3H2(g)  2NH_3(g) 
   2. Step II:
      4NH_3(g) + 5O_2(g) → 4NO_(g) + 6H₂O_(l) 
      4NO_2(g) + O_2(g) + 2H₂O_(l) → 4HNO_3(aq) 
4. It is a reducing agent
