Nettet13. nov. 2024 · The Le Chatelier principle tells us that in order to maximize the amount of product in the reaction mixture, it should be carried out at high pressure and low temperature. However, the lower the temperature, the slower the reaction (this is true of virtually all chemical reactions.) NettetThis change reduces the Fe+3 concentration, so in accord with Le Chatelier’s Principle, some FeNCS+2 dissociates to replace some of the Fe+3 removed by reaction with Cl-.
