    The potential energy diagram for a reaction \[MnO_{4}^{-}\] is given below \[Mn{{O}_{2}}\] of the reaction corresponds to the energy:

    A)  a                                            

    B)  b                    

    C)                         c           

    D)         \[MnO_{4}^{-}\]                 

    Correct Answer: C

    Solution :

    Activation energy of forward reaction = a Activation energy of backward reaction = b \[\therefore \] Heat of reaction  \[=b-a=c(b>a)\] \[\Rightarrow \] reaction is exothermic.
