This video tutorial explains how to derive a rate law using steady state approximation kinetics. It covers the equilibrium of reactants A and B with intermediate C, which can branch into products D and E. The tutorial details the derivation of the rate law for intermediate C, using rate constants K1, K-1, K2, and K3. It then calculates the rates of formation for products D and E, highlighting the differences in rate constants. The video concludes with a summary of handling branched reaction sequences using steady state approximation.
