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)`?A. `1.6 mol L^(-1)`B. `0.8 mol L^(-1)`C. `0.4 mol L^(-1)`D. `0.6 mol L^(-1)` |

Answer» Correct Answer - C `{:(SO_(2)(g),+,NO_(2)(g),hArr,SO_(3)(g),+,NO(g),),(1,,1,,1,,1,"Initial conc"),(1-x,,1-x,,1+x,,1+x,"At Eq."):}` `K=([SO_(3)][NO])/([SO_(2)][NO_(2)])=((1+x)(1+x))/((1-x)(1-x))` `16=((1+x)^(2))/((1-x)^(2))rArr((1+x))/((1-x))=4` or `x=0.6` `[NO_(2)]=1-x=1-0.6=0.4 "mol" L^(-1)` |
