Construct the cell corresponding to the reaction : `3Cr^(2+)(1M)rarr

Construct the cell corresponding to the reaction : `3Cr^(2+)(1M)rarr 2Cr^(3+)(1M)+Cr(s)` and predict if the reaction is spontaneous. Also calculate the following (i) `Delta H` and `Delta S` of the reaction at `25^(@)C`. Given `E_(Cr^(3+),Cr)^(@)=0.5 V, E_(Cr^(3+),Cr^(2+))=-0.41 V` `Delta G` of the reaction at `35^(@)C =-270.50 kJ`
