Thermodynamics ●When△ Go is negative, the reaction is exergonIc(放能的), Chas a favorable equilibrium constant,/and can occur spontaneously. When/4Go is positive,the reaction is endergonic(吸能的), has an unfavorable equilibrium constant and cannot occur spontaneously. ●放能不等于放热,同样,吸能也不等于吸热 因为体系与环境间还可以有功的交换 (等压过程的膨胀与收缩)z When △G0 is negative, the reaction is exergonic （放能的） , has a favorable equilibrium constant, and can occur spontaneously.
