在近几年的高考中,“绝热条件”下的化学平衡问题逐渐得到青睐。“绝热条件”是指反应体系与外界无热量交换,体系的温度在反应过程中随反应的热量变化将会升高或降低,与在恒温条件下相比,“绝势条件”下,可逆反应所达到的平衡状态还将受到反应自身能量变化的影响. In recent years, college entrance examination, “adiabatic conditions ” under the chemical equilibrium problem has been favored. “Adiabatic condition ” refers to the reaction system without heat exchange with the outside world, the temperature of the system in the reaction process will change with the reaction of heat will increase or decrease, compared with the constant temperature conditions, " , The equilibrium state reached by the reversible reaction will also be affected by the change in energy of the reaction itself.
