The decomposition of N2O5 is a first-order reaction: N2O5 ? 2NO2 + ½ O2
a. At 25 °C, it takes 5.2 h for the concentration to drop from 0.120 M to 0.060 M. Calculate the rate constant for the
decomposition of N2O5.
b. Express the rate of the reaction with respect to each of the reactants and products. (In other words, write a rate
expression, Rate = ... )
c. Sketch plot showing how the concentration of NO2 changes with time
