Description
technical field [0001] The invention is a device and a method for measuring the catalytic decomposition reaction rate of hydrogen peroxide, and belongs to the innovative technology of the device and method for measuring the catalytic decomposition reaction rate of hydrogen peroxide. Background technique [0002] At present, the devices commonly used in physical and chemical laboratories to measure the reaction rate and half-life of hydrogen peroxide catalytic decomposition all use the gas volume method to measure the volume of gas produced in the reaction, that is, under the condition that the pressure generated by the reaction is equal to the atmospheric pressure, measure The volume of the gas generated during the reaction changes with time, and the reaction rate constant is calculated from the relationship between the volume of the gas and the concentration of the reactant. In order to measure the volume produced by oxygen for a certain period of time, use such as figure ...
