One of the least abundant nitrogen oxides in the atmosphere is dinitrogen pentoxide. One reason concentrations of this oxide are low is that the molecule is unstable and rapidly decomposes to N2O4 and O2: 2N2O5(g)  →  2N2O4(g)  +  O2(g)    A kinetic study of the decomposition of N2O5 at a particular temperature yielded the data in the following Table. Assume that the decomposition of N2O5 is first order in N2O5. Test the validity of your assumption. Determine the value of the rate constant.

Question

One of the least abundant nitrogen oxides in the atmosphere is dinitrogen pentoxide. One reason concentrations of this oxide are low is that the molecule is unstable and rapidly decomposes to N2O4 and O2: 2N2O5(g)  →  2N2O4(g)  +  O2(g)    A kinetic study of the decomposition of N2O5 at a particular temperature yielded the data in the following Table. Assume that the decomposition of N2O5 is first order in N2O5.

  1. Test the validity of your assumption.
  2. Determine the value of the rate constant.
