WebFeb 18, 2013 · From a mole balance we know that at steady state \(0 = F_{A0} - F_A + V r_A\). That equation simply states the sum of the molar flow of A in in minus the molar flow of A out plus the molar rate A is generated is equal to zero at steady state. This is directly the equation we need to solve. We need the following relationship: \(F_A = v0 C_A\) http://www.seas.ucla.edu/stenstro/Reactor.pdf
