At a certain temperature, `K_(c)` for
`SO_(2)(g)+NO_(2)(g) hArr SO_(3)(g)+NO(g)`
is `16`. If we take one mole of each of all the equilibrium concentration of NO and `NO_(2)`?

Answer

A, B, D

Explanation

`{:(SO_(2)(g),+,NO_(2)(g),hArr,SO_(3)(g),+,NO(g)),(1,,1,,1,,1),(,,,,,,"moles at t=0"),((1-x),,(1-x),,(1+x),,(1+x)),(,,,,,,("moles at equilibrium")):}`
`:. K_(c)=(((1+x)/V)((1+x)/V))/(((1-x)/V)((1-x)/V))=((1+x)^(2))/((1-x)^(2))`
`:. ((1+x)^(2))/((1-x)^(2))=16 " " ( :' K_(c)=16)`
`:. ((1+x))/((1-x))=4` or `x=3/5=0.6`
`:'` Volume `=1L`
`:. [SO_(2)]=[NO_(2)]=1-x=1-0.6=0.4 "mol" L^(-1)`
`[SO_(3)]=[NO]=1+x=1+0.6=1.6 "mol" L^(-1)`
