    Select Question Language :


    Directions: The following question is based on the paragraph given below.
    Redox reactions play a pivotal role in chemistry and biology. The values of standard redox
    potential (E°) of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is an 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° (V with respect to normal hydrogen electrode) values. Use the data obtain the correct explanations to next three questions.
    l2 + 2e  2l                                Eo = 0.54
    Cl2 + 2e  2Cl                       Eo = 1.36
    Mn3+ + e  Mn2+                     Eo = 0.77
    O2 + 4H+ + 4e–   2H2O             Eo = 1.23
    While Fe3+ is stable, Mn3+ is not stable in acid solution because

    Options :-

    1. O2 oxidises Mn2+ to Mn3+
    2. O2 oxidises both Mn2+ to Mn3+ and Fe2+ to Fe3+
    3. Fe3+ oxidizes H2O to O2
    4. Mn3+ oxidizes H2O to O2
