Series Reactions in a Batch Reactor

Two first-order, liquid-phase reactions A –> B –> C take place in an isothermal batch reactor. The reactor initially contains only A at a concentration of 2 mol/L. The activation energy Ea2 of the second reaction (155 kJ/mol) is higher than the activation energy Ea1 of the first reaction (145 kJ/mol). Vary the temperature of the reaction with a slider. Select Display: “selectivity” to plot selectivity CB/CC versus time. The selectivity changes with temperature because the reactions have different activation energies.
