1.	1.50 moles each of hydrogen and iodine were placed in a sealed 10 litre container maintained at 717 K. At equilibrium `1.25` moles each of hydrogen and iodine were left behind. The equilibrium constant, `K_(c)` for the reaction , `H_(2)(g)+I_(2)(g) hArr 2Hl(g)` at 717 K isA. `0.4`B. `0.16`C. 25D. 50
Answer» Correct Answer - 2 `{:(,H_(2)(g),+,l_(2)(g),hArr,2Hl(g)),(t=0,1.5,,1.5,,0),(t-t_(eq),1.5-x,,1.5-x,,2x):}` We know,` 1.5-x=1.25`,or`" "x=25` `K_(c)=((.5)^(2))/((1.25)^(2))=.16`
