In te gas phase reaction, C_(2)H_(4)+H_(2)hArr C_(2)H_(6), the equlibrium constant can be expressed in units of

Answer»

`"LITRE"^(-2)"MOLE"^(-1)`
litre `"mole"^(-1)`
`"mole"^(2)"litre"^(2)`
mole `"litre"^(-1)`

Solution :`K=([C_(2)H_(6)])/([C_(2)H_(4)][H_(2)])=(["mole/litre"])/(["mole/litre][mole/litre"])`
`="litre/mole. or litre mole"^(-1)`
