Nitric acid is the most important oxyacid formed y nitrogen .It is one of the major industial chemicl and is widely used. Nitric acid is manufactured by the catalytic oxidation of ammonia in what is known as OSTWALD PROCESS which can be represented by the sequenve of reactions shown below:
`4NH_(3)(g) +5O_(2)(g) underset("Catalyst")overset(Pt//Rh)rarr 4NO(g)+6H_(2)O(g) " "...(i)`
`2NO(f) + O_(2)(g) overset(1120 K) rarr 2NO_(2)(g)" "...(ii)`
`3NO_(2)(g)+H_(2)O(l) rarr 2HNO_(3)(aq)+NO(g)" "...(iii)`
The aqueous nitric acid obtained by this method can be concentrated by distillation to ~ 68.5 % by weight . Further concentrated to 98% acid can be achieved by dehyration with concentrated sulphuric acid. If 180 litre of water completely reacts with `NO_(2)` produced to form nitric acid according ot the above reactions then the volume of air at STP containing 20% of `NH_(3)` is :(`rho_(H_(2)O)=1 gm//ml`)

Name the type of reaction represented by the following equation : 4NH_(3)(g) +5O_(2)(g) to 4NO(g) + 6H_(2)O(g)
Nitric acid is the most important oxi-acid formed by nitrogen. It is one of the major idustrial chemicals and is widely used. Nitric is manufactured by ostwald process in which catalytic oxidation of ammonia is done in following sequence as shown by reactions 4 NH_(3) (g)+50_(2)(g) overset("Pt/Rh")underset("Catalyst")(rarr) 4 NO(g)+6 H_(2)O(g) ...(i) 2NO(g)+O_(2)(g) overset(1120 K)(rarr) 2NO_(2)(g) ...(ii) 3 NO_(2)(g)+H_(2)O(l) rarr 2 HNO_(3)(aq)+NO(g) ...(iii) In this process the aqueous nitric acid is obtained which can be concentrated by distillation to ~ 68.5% by weight. Then concentration to 98% acid can be achieved by dehydration with concentrated sulfuric acid. If 170 kg of NH_(3) is heated in excess of oxygen, then the volume of H_(2)O(l) produced in 1st reaction at STP is (rho_(H_(2)O)=1 g//mL)
