Aluminium metal is purified by :

Options

A. `0.331M`
B. `0.033M`
C. `0.133M`
D. `1.33M`

Answer

3

Explanation

`Q_(c)=(1xx1)/(1xx1)=1`
`:'Q_(c)gtK_(c)` sor reaction will proceed in backward direction `:`
`{:(,A_(2)(g),+,B_(2)(g),hArr,C_(2)(g),+,D_(2)(g)),("Conc. eqm",(1+x)/(10),,(1+x)/(10),,(1+x)/(10),,(1-x)/(10)):}`
`0.25=(((1-x)/(10))^(2))/(((1+x)/(10))^(2))" "rArr" "x=0.333`
`[A_(2)(g)]=(1+x)/(10)=(1.333)/(10)=0.133`
