    Chemical reactions with very high \[{{E}_{a}}\] values are generally:

    A)  very fast            

    B)  very slow

    C)  moderately fast              

    D)  spontaneous

    Correct Answer: B

    Solution :

    Reactions having low \[{{E}_{a}}\] are fast reactions and reactions having high \[{{E}_{a}}\] are slow reactions. If the \[{{E}_{a}}\] is high, then the number of effective collisions will be small and the reaction will be slow.
