WebHigh pressures (concentrations) of reactants are used, ~150−250 atm, to shift the equilibrium right, favoring product formation. Ammonia is continually removed (collected) from the equilibrium mixture during the process, lowering its concentration and also shifting the equilibrium right. WebDec 2, 2024 · The states which contain the species (whose concentration is changed) are affected whereas others are not, so the Gibbs free energies of activation are changed, which means the rate constants are changed, which can change the rate determining step. But if concentrations can affect k r then it seems like the rate law cannot be written like that.
