a. Fe is more reactive than Cu hence replaces Cu from CuSO4. Due to this reaction holes develop in Fe tank
Fe + CuSO4 -----> FeSO4 + Cu
while Ag is less reactive than Cu and can't replace Cu from CuSO4. So CuSO4 can be stored in Ag tank.
b. C6H12O6 + 6O2 ----- > 6CO2 + 6H2O + energy
energy released during formation of new bonds is more than energy required to break bonds in reactants. Thus energy is released during the reaction hence is exothermic.
