8. Using the ion-electron half-reactions, write equations in molecular form. Write down from the reference tables (see Appendix 3) the value of the standard potentials of redox pairs (E0) and set the oxidizing agent and reducing agent. Write down the expression for the equilibrium constant of the reaction (K). Based on E0, calculate K and determine the direction of the reaction (see the option in Table 6)
reactants
