Question

The decomposition of N2O5 in a solution of carbon tetrachloride occurs as shown in the balanced chemical equation

below:

2N2O5(soln) → 4NO2(soln) + O2(soln)

This reaction is a first order process with a rate constant of 4.82 x 10-3

s-1.

If the initial concentration of N2O5 is 0.150 M, how much N2O5

will remain after 300.0 seconds?

0.0353 M

0.0553 M

0.0762 M

5.00 x 10-4 M

0.104 M
