    What is the effect of temperature on the rate constant of a reaction? How can this temperature effect on rate constant be represented quantitatively?
    Ans : The rate constant is nearly doubled with a rise in temperature by 10° for a chemical reaction.

    The temperature effect on the rate constant can be represented quantitatively by Arrhenius equation,



    where, k is the rate constant,

    A is the Arrhenius factor or the frequency factor,

    R is the gas constant,

    T is the temperature, and

    Ea is the energy of activation for the reaction
