【摘要】 对于二级反应 A+B→产物 当一个反应物的浓度大大过量时,通常按假一级反应处理。本文对此反应的过程和假一级近似中的误差进行一些讨论并提出定量计算相对误差的公式。蔗糖转化反应表明,这个公式是合理的。更多还原

【Abstract】 The second-order reaction, A + B——products, can often be approximated as a pseudo first-order reaction when either of the reactants is in large excess. The course of the reaction and the error in the pseudo first-order approeimation were discussed.The formula used to calculate the relative error quantitatively was presented and proved to be rational by the inversion reaction of sucrose.更多还原
