5. With a Catalyst: 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 ...
The Arrhenius equation can be used to compute the activation energy of a reaction from experimental kinetic data. A convenient approach to determining the Ea for a reaction involves the measurement of k at two or more different temperatures. It uses a modified version of the Arrhenius equation th...
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 for a reaction at the temperature T K was found to be 2.303 RT J/mol−1. The ratio of the rate constant to the Arrhenius factor is: View Solution Q3 The activation energy for a reaction at the temperature TK was found to be 2.303 RTJmol−1. The ratio of ...
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...

Dependences, that can be used for approximate assessments of reaction activation energy (AE) values during heterogeneous catalysis, are suggested. The assessments are based on the application of the law of conservation of momentum of species involved in the reaction. It is assumed that as a result...
The reaction between atomic hydrogen and hydroxide ion in aqueous solutions H + OH e/sub eq/ + H2O has been studied by pulse radiolysis. The rate constant was measured at pH 11.7 and 12 by following the growth of the hydrated electron absorption at 600 nm. The activation energy of the re...
