Abstract This paper designed a simple device for measuring reaction rate by controlling temperature, and determined the reaction rate of zinc and dilute sulfuric acid with or without chloride ion effect at different temperatures. The conclusion was that the higher the temperature, the weaker the chloride effect. The temperature range of chloride ion effect was found:the reaction rate of zinc and dilute sulfuric acid was accelerated by chloride ion in the temperature range from 27℃ to 57℃, and the effect of chloride ion on accelerating the reaction rate was weakened in the temperature range from 62℃ to 87℃.
