    Consider the given plot of enthalpy of the following reaction between\[A\]and\[B.A+B\to C+D.\] Identify the incorrect statement,

    A) C is the thermodynamically stable product

    B) Formation of A and B form C has highest enthalpy of activation.

    C) Activation enthalpy to form C is\[5\,kJ\,mo{{l}^{-1}}\]

    D) D is kinetically stable product.

    Correct Answer: C

    Solution :

    \[{{E}_{a}}=(d\to c)=15-0=15\]
    \[{{E}_{a}}=(A+B)\to C=15\]
    \[{{E}_{a}}=(A+B\to D)=10\]
    \[{{E}_{a}}=C\to (A+B)=20.\]
