Steric effects in rate constants for bimolecular dissociation 离解反应速率常数中的方位因素
The rate constant of the surface electrochemical reaction was determined as ,表面电极反应速率常数
Constant of reaction rate 反应速率常数
The variation of the return rate constant k with different absolute temperature t deviates arrhenius empiric equation 反应速率常数随绝对温度的变化基本上符合阿累尼乌斯定理。
The photocatalytic dynamics of two important and representative organic substances - methylene blue and methylene orange . those two organic substances could be directly degraded without tio _ ( 2 ) by uv lamp . the type of reaction belonged to typical first - degree reaction 由实验可知,在无光催化剂时,紫外线可直接降解有机物,其反应机理属于典型的一级反应,降解甲基橙和甲基蓝的反应速率常数分别为0 . 0013min ~ ( - 1 )和0 . 004min ~ ( - 1 ) 。
The kinetic characteristics of the electrochemical oxidation of adrenaline to adrenochrome was studied by uv - vis spectroscopy . the measurements showed that the electrooxidation of adrenaline to adrenochrome was typical of the first order reaction and the average apparent rate constant is 1 . 92110 以紫外-可见分光光度法为主要手段,研究了肾上腺素电氧化生成肾上腺素红的反应动力学特征。研究结果表明:该反应具有一级反应的动力学特征,且反应的表观反应速率常数的平均值为1 . 92110
The type of photocatalytic reaction was first - degree reaction which was not very typical , and the reaction speed constants could be used to judge the efficiency of photocatalysis . the tio _ ( 2 ) films were prepared on glasses by magnetron sputtering . the influences on the tio _ ( 2 ) films properties of various o _ ( 2 ) partial pressure , various sputtering power , various heat treatment method and n was studied too 加入光催化剂tio _ 2粉末以后,光催化反应速率增幅较大,其过程可以认为是准一级反应,可以用一级反应速率常数来表征光催化效率,降解甲基橙和甲基蓝的反应速率常数分别为0 . 003min ~ ( - 1 )和0 . 35min ~ ( - 1 )左右。
