摘要
由实验获得CH+ →0时,蔗糖转化反应的比速率k0 为零。H+ 离子的催化比速率kH+ 和积数n分别是1.413×10- 2m in- 1和1.0。酸催化比速率方程为k/min- 1=1.413×10- 2kH+ /m ol.dm- 3,适用于CH + ≥0.9000mol.dm - 3的任意浓度。
If the C H + →0 ,specific rate k 0 is tantamount to zero of transmation reaction of the cane suge, the specific rate k H + and the order n H + of catalysis of the H + ions separatly are 1.413×10 -2 min -1 and 1.0 is got by the experiments. Hence, the specific rate equation of acid catalysis is taken as k /min -1 =1.413×10 -2 C H + /mol.dm -3 .It applies to wilful concentrations of C H + ≥0.9000mol.dm -3 .
