  • question_answer
    Consider the given plots for a reaction obeying Arrhenius equation \[\left( 0{}^\circ C<T<300{}^\circ C \right)\]:  (K and \[{{E}_{a}}\] are rate constant and activation energy, respectively) Choose the correct option: [JEE Main Online Paper (Held On 10-Jan-2019 Morning]

    A) I is right but II is wrong

    B)                  Both I and II are correct

    C)                  Both I and II are wrong

    D)                  I is wrong but II is right

    Correct Answer: B

    Solution :

    \[K=A{{e}^{-{{E}_{a}}/RT}}\] On increasing activation energy, K decreases & on increasing temperature K increases.
