The concentrations of five species are plotted, as a function of dimensionless time, for three irreversible, elementary, liquid-phase reactions in an isothermal batch reactor. Use sliders to change the dimensionless rate constants for each reaction. The initial amounts of and in the reactor are 10 mol and 5 mol, respectively. Use buttons to plot just one concentration or all five together. The reactions are , , and .
