前者异构化为吸热反应,后者为放热反应。
The experimental results indicated that the changes of height and temperature of the small endothermal peak appearing at 310-325k with storing time is relative to the cooling conditions.实验表明,在310 ~ 325 K出现的热焓松弛峰的峰高和峰温随存放时间的变化与冷却条件有关。
When the concentration of benzoic acid was high, the adsorption was an endothermal process with the system's entropy increasing, and the increase of temperature did benefit to the process.当苯甲酸浓度较高时,吸附为吸热过程,体系熵增加,升温有利于吸附。
