Redox reactions play a pivoted role in chemistry and biology. The values of standard redox potential and biology. The values of standard redox potential (E^0) of two half cell reactions decide which way the raction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper gets deposited. Given below are a set of half-cell reactions (acidic medium) along with their E^0 (V with respect to normal hydrogen eletrode ) values. Using this dat obtain the correct explanations to Questions I_2+2e^_ rarr2I^-E^0=0.54 Cl_2+2e^_ rarr2Cl^-E^0=1.36 Mn^(3+)+e^_ rarrMn^(2+)E^0=1.50Fe^(3+)+e^_ rarrFe^(2+)E^0=0.77O_2+4H^++4e^(-) rarr 2H_2OE^0=1.23 Among the following, identifiy the correct statement.
