23 The gaseous isomerization reaction, CH3NC → CH3CN, displays first-order kinetics, namely rate k[CH3NC]. Measurements at 500 K show that the concentration of the reactant has declined to 75% of its initial value after 440 s. How much time will be required for the concentration of CH3NC to drop to 25% of its initial value?
(A) 640 s
(B) 880s
(C) 1320 s
(D) 1680 s
(E) 2120 s.
