The following data were collected from an isothermal (T = 100°C) batch reactor experiment with pure A feed and CA0 = 2.0 M to investigate the kinetics of the liquid phase reaction. Two different reaction mechanisms have been proposed in the literature. One mechanism concludes that the rate should be given by case 1:

The same batch reactor can be used to make the desired amount of one product and then cleaned and a different reaction can be carried out. The amount of reaction for a first-order, isothermal reaction depends on the total number of moles. Diluting a batch reactor does not change the conversion for an isothermal, first-order reaction.

An irreversible gas phase reaction (A rightarrow 5B) is conducted in an isothermal batch reactor at constant pressure in the presence of an inert. The feed contains no (B). If the volume of the gas at complete conversion must not exceed three times the initial volume, the minimum mole percent of the inert in the feed must be

A formulation of the time dependent molar balance equations, one of which is a nonlinear Bernoulli differential equation, is a preliminary step to modeling an isothermal semi-batch reactor with irreversible second-order reactions.
