    The term\[\frac{-dc}{dt}\]in a rate equation refers to:

    A)  the decrease in concentration of the reactant with time

    B)  the concentration of a reactant

    C)  the change in concentration of the reactant

    D)  the velocity constant of the reaction

    Correct Answer: A

    Solution :

     \[\frac{dc}{dt}\]represent the change in concentration of reactant with time. As, in a reaction, concentration of reactant always decrease with time hence, rate of reaction is represented as\[\frac{-dc}{dt}\].
