In a reaction between hydrogen and iodin...

In a reaction between hydrogen and iodine `6.84 mol` of hydrogen and `4.02` mol of iodine are found to be in equilibrium with `42.85` mol of hydrogen iodide at `350^(@)C.` Calculate the equilibrium constant.

Text Solution

Verified by Experts

The correct Answer is:
B, D
`{:(,H_(2),+,I_(2),hArr,2HI),("A equilibrium",0.34,,4.02,,42.85):}`
`K=([HI]^(2))/([H_(2)][I_(2)])=([42.85]^(2))/([6.34][4.02])=72.042`
