Weight gains due to the reaction of iodine vapor with vacuum-deposited silver films have been measured by a quartz crystal microbalance operated at different crystal exciting powers. The reaction rate is found to decreases with increasing exciting power of the crystal. This is explained as the result of increase of reaction temperature from an observation that the rate of this reaction decreases with increasing temperature. The increase of temperature is measured directly, by using thermocouples made by vacuum-deposition of copper and constantan on the crystal, to be about 17℃ and 0.1℃ at the exciting powers of 300 mW and 5 mW in a vacuum. It is concluded that the quartz crystal microbalance can be used without the thermal influence of the vibration for the measurement of weight changes of such reactions as far as it was operated at exciting power as weak as 5 mW.
