Number 2 is correct answers
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.

For reaction
2 A + B ------------> 2 C
Rate = K [ A ]² [ B ]
<span> the order with respect to A is 2 and the order overall is 3.
