(e4qg 8nbvn8l1i/rx s ayer. One substance that reacts with ozone is nitrogen monoxide.
The reaction is: $O_3(g)$+$NO(g)$→$O_2(g)$+$NO_2(g)$
1.Use the data to determine the order of the reaction for each reactant, and the overall order of the reaction.
2.Give the rate expression for this reaction.Calculate$\kappa$for this reaction using a set of data from the table and determine its correct units.
3.What does the value of $\kappa$ suggest about this reaction in the atmosphere?
4.Suggest with a reason, a possible mechanism consistent with your rate expression.
In an experiment, the following data were collected at $25^{\circ}C$:
Trial | Concentration of $O_3$($mol$ $dm^{-3}$) | Concentration of $NO$($mol$ $dm^{-3}$) | Rate of reaction ($mol$ $dm^{-3}s^{-1}$) |
1 | $3.00\times 10^{-3}$ | $1.00\times 10^{-3}$ | $6.60\times 10$ |
2 | $6.00\times 10^{-3}$ | $1.00\times 10^{-3}$ | $1.32\times 10^{2}$ |
3 | $9.00\times 10^{-3}$ | $1.00\times 10^{-3}$ | $1.98\times 10^{2}$ |
4 | $9.00\times 10^{-3}$ | $2.00\times 10^{-3}$ | $3.96\times 10^{2}$ |
5 | $9.00\times 10^{-3}$ | $3.00\times 10^{-3}$ | $5.94\times 10^{2}$ |
