    Select Question Language :


    The decomposition of dinitrogen pentaoxide following the first order kinetics is given by

    0.2 mole of N2O5 is taken in a vessel of 1 L capacity and heated to a certain temperature (K) at which reaction begins. The concentration of N2O5 is measured at different intervals of time by withdrawing samples of reaction mixture. A plot of [N2O5] v/s t is shown in figure below:

    If the value of rate constant k is determined from slope of linear plot and the slope of straight line is -5 x 10-2 min-1, then what is the half-life of the reaction?

    Options :-
