Assignment 1: Cyclopentadiene (A1) reacts with butadiene (A2) to form vinyl dicycloheptene (A3) according to the regularities of the second-order reaction. Intermediate A3 transforms into tetrahydroindene (first-order reaction). At a certain temperature, under initial concentrations Callo) =1.5 mol/L and CA2) 5 mol/L half of the initial cyclopentadiene reacted in 2.2 h. By that moment concentration of A3 had been increasing and after some time tmax it has reached its maximum value of 0.7 mol/L. Plot the concentration of A1 upto 4.5 h reaction
