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 first order homogeneous gaseous decomposition A 2.5R is carried out in an isothermal batch reactor at 1 atm with 20% inerts, and the volume increased by 60% in 20 min. In a constant volume reactor, find the time required for the presence to reach 8 atm if the initial pressure of 5 atm.

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.

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. The molar balance equations obtained in this fashion are classified as first order nonlinear ODEs.

Thus far in our study of chemical kinetics, we have considered reactions in isothermal batch reactors, in which reactions taking place in closed containers maintained at a constant temperature.
