Nitric oxide (NO) is the catalyst used for the oxidation of SO2 to SO3 in the lead chamber process for the manufacture of sulphuric acid.

<h3>Nitric oxide</h3>

The volume of flask =10 liter

(a) 2SO2+O2⇌2SO3K=100

At an x a

end a/10 x/10 a/10

const KC=(x/10)(a/10)2(a/10)2=100

1001=10x⇒x=1/10

0.1 moles of O2 are present .

(b) 2SO2+O2⇌2SO3

At an x 2a

eq a/10 x/10 2a/10

contact

KC=(x/10)(a/10)2(102a)2⇒x/104=100

x=4/10=0.4 moles of O2.
