1 mole of H_(2) and 2 moles of I_(2) are taken initially in 2 litre vessel. The number of moles of H_(2) at equlibrium is 0.2. Then the number of moles of I_(2) and HI at equliberium are

Answer»

`1.2,1.6`
`1.8,2.4`
`0.4,2.4`
`0.8,2.0`

Solution :At EQULIBRIUM NUMBER of moles of `H_(2)=0.2` moles 0.8 moles of `H_(2)` reacts with `(2-0.8)`moles of `I_(2)` to from `(2xx0.8)` moles of HI
`H_(2)+I_(2)hArr2HI`
`{:("Inital no.",1,2,0),("of MOLE",,,),("No of moles"0.,2,,(-20.8)2xx0.8),("at equlibrium",,=1.2,=1.6):}`
