When a catalyst is introduced, it lowers the height of the peak in the energy profile. This means that the energy required to reach the transition state is reduced, resulting in a lower activation energy. 6. Effect on Reaction Rate: Since the activation energy is lower with a catalyst, ...
化学平衡反应中使用催化剂可以降低反应的活化能 这种说法是否正确,原话为They reduce the activation energy of the reaction.不是说催化剂不影响最终产物吗,既然最终产物(浓度)不变,反应所产生的能量怎么会变化呢 相关知识点: 试题来源: 解析 正确啊,当然不排除逆催化剂,提高活化能 根据盖斯定律,化学反应的总过程...
ACTIVATION ENERGY: PLAYS AN IMPORTANT ROLE IN A CHEMICAL REACTIONAshoke Hazra
Question. The activation energy for a simple chemical reaction A = B is E a in forward direction. The activation energy for reverse reaction(a) is negative of Ea(b) is always less than Ea(c) can be less than or more than Ea(d) is always double of Ea. 相关知识点: 试题来源: ...
The activation energy of the reaction has been determined over the temperature range 15-60C as 6.3 +/- 0.6 kcal/mol (26.4 +/- 2.5 kJ/mol). From this value and the activation energy of the reverse reaction, the e/sub aq/ enthalpy of formation H/sub f/ = -32.6 +/- 1.6 kcal/mol ...
