Consider the reaction below: N2O4 (g) → 2 NO2 (g) Which of the following techniques be used to determine the rate law is second order with respect to the concentration of dinitrogen tetroxide? O A graph of In([N204]) versus time will produce a straight line. A graph of [N204] versus time will produce a curved line. A graph of (N2O.) versus time will produce a straight line. The balanced chemical equation tells us that the reaction is first order with...
