Abstract 1stOpt software was used in physical chemical experiment of sucrose hydrolysis reaction rate constant, the start time of reaction and the optical rotation of final reaction didn't need to determined, the rate constant of reaction can be obtained by nonlinear curve fit simply and conveniently without programming and formula transformation. This work avoided the artificial error caused by the traditional data processing method, and could supplement and improve the teaching of physical chemistry experiment.
