Two ways to determine equilibrium position in organic chemistry

WebThus, one way to determine whether the reactants or products are favored in an equilibrium is to compare the stabilities of two negative charges on opposite sides of the equilibrium-arrows. Whichever side has the more stable negative charge is favored because this side is lower in energy. WebTo ensure the greatest possible yield of thermodynamic products, the reaction should be carried out at a temperature of 40°C or greater. This is known as thermodynamic control. … can states issue their own currency
