Product description
5. Glucose mutarotation is catalyzed by acids and bases and is of the first order in terms of glucose concentration. If perchloric acid is used as a catalyst, then the concentration of hydrogen ions can be considered equal to the concentration of perchloric acid, and the effect of perchlorate-non can be ignored, since it is a very weak base. The following first-order rate constants were obtained:
[HClO4], M 0.0010 0.0048 0.0099 0.0192 0.0300 0.0400
k*104, min-1 1.25 1.38 1.53 1.90 2.15 2.59
Calculate the constants in the equation k=k0 kH [H ].
