a)The order of this ozone decomposition reaction is order because .b)The rate constant for this ozone decomposition reaction is (include units!)c)How many minutes will it take before half of the original ozone concentration ([O3]0) is depleted?

a). Second order reaction.

b).

c).  

Explanation:

a). The order of the reaction of ozone decomposition is second order reaction.

It will be second order because the plot between the Inverse of Concentration versus Time will be a straight line.

b). Calculating slope by

Slope, k =

Thus we see that the slope of the curve will be rate constant.

Therefore, rate constant =

c). We know half life ,

k =

Putting the values, we get
