90. Solving a chemistry problem

4. Taking into account the values of the standard redox potentials of two redox pairs. indicate in which direction the reaction proceeds between them. Write reaction equations in ionomolecular and molecular forms. Determine the molar mass equivalents of the oxidizing agent and reducing agent. Calculate the equilibrium constant and evaluate the completeness of the reaction.
PbO2 H /Pb2 and Cl2/2SG.
