Suppose that the silver-silver chloride electrode in the figure is replaced by a saturated calomel electrode. Calculate the cell voltage if [Fe2+]/[Fe3+] = 5.0 10-3. V
Problem- Bond breaking energy of F-F= 38kcal/mol; Cl-Cl= 58kcal/mol; Br-Br= 46kcal/mol; I-I= 36kcal/mol? Could someone explain why the bond breaking energy doesn't decrease as we go down this group but instead random and F and I has a similar valu..
For the reason that lone pairs are larger than bonding pairs, lone pair-lone pair interactions are greater than line pair-bonding pair interactions, which are in turn larger than boning pair- bonding pair interactions
