1 A batch reactor is a perfectly mixed vessel where a chemical reaction is carried out for a given time. Typically, there is no input or output flow and the process is time-dependent (see Figure 1). c(t) Figure 1 (a) Given a first order chemical reaction with rate R = -kc, where k is the reaction constant and c the concentration of a given reacting species and...
