(B) The |m| (m = slope) of the curve of the first reaction is smaller than that of the second reaction in the Arrhenius plot.
(C) With the same reaction time, adding a catalyst to catalyze the second reaction can improve the yield of C.
(D) The apparent activation energy of the whole sequential reaction is closer to the activation energy of the second reaction.
(E) The second reaction has a lower activation energy.
