Cyclobutane can decompose to form ethylene:

The cyclobutane concentration can be measured as a function of time by mass spectrometry (a graph follows).

(a) Write an expression for the rate of reaction in terms of a changing concentration.

(b) Calculate the average rate of reaction between 10 and 30 seconds.

(c) Calculate the instantaneous rate of reaction after 20 seconds.

(d) Calculate the initial rate of reaction.

(e) Calculate the instantaneous rate of formation of ethylene 40 seconds after the start of the reaction.
