This is most often seen when two or more reactants are involved. Thus if the reaction (1) A + B → products is first-order in both reactants so that (2) rate = k [ A] [ B] real analysis textbook freeWebthe moles reacted from the moles accumulated in the CSTR. Consequently, we must use concentration rather than conversion as our variable in the balance equation. For liquid-phase (υ = υ 0) reactions with constant overﬂow (V = V 0), using τ = V 0 / υ 0, we can transform Equation (6-8) to (6-9) For a ﬁrst-order reaction (– r A = kC A ... real anarchy government
