###### FREE Expert Solution

$Average \ rate = \frac {Δ[ \ ]}{Δt}$

Because we lose reactants and gain products, we are losing $[N_2O_2]$, and our equation becomes: $Average \ rate = \frac{-Δ[ \ ]}{Δt}= \frac{-Δ[N_2O_2 ]}{Δt}$ Also, remember that $Δ= final - initial$, and that whatever the coefficient we have for the reactant, we will put that number on the bottom!

###### Problem Details

The decomposition of N2O5 can be described by the equation.

2N2O5 (soln) →  4NO2 (soln) + O2 (g)

Given this data for the reaction at 45°C in carbon tetrachloride solution, calculate the average rate for each successive time interval.

t(s)                [N2O5] (M)

0                    2.10

195                1.86

556                1.48

825                1.25

i) Interval: 0 s to 195 s

Reaction rate= _____M/s

ii) Interval: 195 s to 556 s

Reaction rate= _____M/s

iii) Interval: 556 s to 825 s

Reaction rate= _____M/s
