Calculating the average reaction rate : Calculate the average rate of decomposition of `N_(2)O_(5)` by the reaction
`2N_(2)O_(5)(g)rarr4NO_(2)(g)+O_(2)(g)`
during the time interval from `t=600s` `t=1200s`, using the following data:
Time , `[N_(2)O_(5)]`
`600s` , `1.24xx10^(-2)M`
`1200s` , `0.93xx10^(-2)M`
Strategy : Calculater a `Delta` quantity in concentration, `[N_(2)O_(5)]`, by taking the final value minus the value. Then, divide it by the time interval, `Delta t`.

Answer

`5.166xx10^(-4) Ms^(-1)`
