Consider the following statements :
Roasting is carried out to :
1. Convert sulphide into oxide
2. Melt the ore
3. Remove moisture, water of hydration and expel organic matter
4. Remove sulphur and arsenic in the form of volatile oxides
Out of these statements :

A

`0.38`

B

`0.23`

C

`0.61`

D

`0.55`

Text Solution

Verified by Experts

The correct Answer is:
1
`{:(N_(2)O_(4)hArr,2NO_(2),,P+P=0.4atm,,P_(N_(2))=0.6atm),(P_(0),-,,K_(p)=(P^(2))/(P)=0.25,,),(P_(0)-P'//2=P,P,,P=4P^(2),,),(4P'^(2)+P'-0.4=0,,,P=0.18,,),(P'=0.22,,,,,):}`
Degree of dissociation `=(P'//2)/(P_(0))=(0.11)/(0.18+0.11)=0.38`
