The data below show the concentration of N2O5 versus time for the following reaction: N2O5(g)→NO3(g)+NO2(g) Time (s) [N2O5] (M) 0 1.000 25 0.822 50 0.677 75 0.557 100 0.458 125 0.377 150 0.310 175 0.255 200 0.210 Predict the concentration of N2O5 at 280 s .

The following reaction was monitored as a function of time:
AB→A+B
A plot of 1/[AB] versus time yields a straight line with slope 5.8×10−2 (M⋅s)−1 .

You may want to reference (Page) section 13.4 while completing this problem.

C.What is the half-life when the initial concentration is 0.53 M ?

Express your answer using two significant figures.

D. If the initial concentration of AB is 0.280 M , and the reaction mixture initially contains no products, what are the concentrations of A and B after 80  s ?

Express your answers numerically using two significant figures, separated by a comma.
