Problem 1 50 Points The Reaction 1 Between Cyclopentadiene And Dimethyl Fumarate Dmf Has Been Performed At Room T 1 (57.06 KiB) Viewed 27 times
Problem 1. [50 points] The reaction (1) between cyclopentadiene and dimethyl fumarate (DMF) has been performed at room temperature. The measured DMF concentration (DMF is the second reactant), in mol/liter is shown in the table. H COCH COCH. H - H CO.CH. 1a.

Use the following scheme (to avoid the complicated compound names) A+B_C 2AD Write the rate equations for these reactions in terms of extents of reactions. CHOC H (1)
1d. [10 points] The rate constants defined at 1c are k₁ = 9.63 104 L/sec mol, k2= 3.71 10-4 L/sec mol and k3 = 4.11 10-³ L/sec mol. Take the initial concentrations to be A(0) = 1 mol/L, B(0) = 1 mol/L, C(0) = 0 and D(0) = 0. Calculate the concentrations as a function of time and and plot A(t), B(t), C(t) and D(t) as functions of t on the same graph.
