The standard emf of galvanic cell involving 3 moles of electrons in its redos reaction is 0.59V. The equilibrium constant for the reaction of the cell is

Answer»

`10^(25)`
`10^(20)`
`10^(15)`
`10^(30)`

Solution :`nFE_("cell")^(@)=2.303TlogK`
`E_("cell")^(@)=(2.303RT)/(nF)log=(0.0591)/(n)logK`
`n=3`
`logK=(0.59xx3)/(0.0591)=29.9`
`K~~10^(30)`.
