Rates

NOTE: The reaction rates in the above mole balances are net rates.

The new things for multiple reactions that build on Figure 4-11 and Table 4-6 areNumber every reactionRate Law for every reactionRelative Rates for every reactionNet Rates of ReactionNumber every reaction Rate Laws for every reaction Relative Rates for each reactionFor a given reaction i Net Rate of Formation for Species A that appears in N reactions,

Stoichiometry

NOTE: We could use the gas phase mole balance for liquids and then just express the concentration as
Flow C_A = F_A/υ₀
Batch C_A = N_A/V₀

Writing Net Rates of Formation

Applications of Algorithm

(1)NOTE: The specific reaction rate k1A is defined with respect to species A.(2)NOTE: The specific reaction rate k2C is defined with respect to species C.

These reactions will be used in the following 5 examples

• Liquid Phase PFR

• Liquid Phase CSTR

• Gas Phase PFR no ΔT

• Gas Phase Membrane Reactor with ΔT

• Liquid Phase Semibatch Reactor
