For a chemical system involving reacting species (such as oligomers) whose molecular formulae are of the form [( E 1 ) a1 ( E 2 ) a2 … ( E M ) aM ] n , where E is an element, both the equilibrium distribution and sensitivity analysis can be computed as for a one‐element system. The resulting simplification means that the former requires the solution of a single polynomial equation, and the latter allows explicit calculation of the relevant sensitivity coefficients. The treatment is illustrated for the catalytic oligomerization of olefins.
