Batch Reactor with Multiple Reactions

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 .

Three liquid-phase reactions take place in an isothermal batch reactor:
, with reaction rate ,
, with reaction rate ,
, with reaction rate ,
where is the concentration of component , is rate of reaction, and is the rate constant.
Mass balances on each component:
where is time, are moles of , and is reactor volume. Initially 10 moles of and 5 moles of are fed into the reactor.
The screencast video at [1] shows how to use this Demonstration.
