i. Plot the data in Table 22.1 for increase in propene concentration with time.

ii. Calculate the rate after 10 minutes (when the propene concentration is 0.50 mol dm^–3) by drawing a tangent.

b. Use the same method to calculate the rate of reaction at propene concentrations of 0.00 mol dm^–3, 0.30 mol dm^–3 and 0.90 mol dm^–3.

c. i. Calculate the concentration of cyclopropane when the concentration of propene is 0.00, 0.30, 0.50 and 0.90 mol dm^–3.

ii. Plot a graph of rate of reaction against [cyclopropane]. Note that the graph is for cyclopropane concentration NOT [propene] as it is the concentration of the reactant that is affecting the rate not the product.
