摘要: 用简单的方法估算了丙酮碘化反应实验中用平均速率代替瞬时速率产生的方法误差,相对误差的绝对值为10-4数量级,并分析了产生误差的原因。

关键词: 丙酮碘化反应, 平均速率, 瞬时速率, 相对误差

Abstract: The methodic error of reaction between acetone and iodine was investigated using a simple and novel method. The relative error was calculated to as low as 10-4. We also give a discussion on the reason causing this error.

Key words: Reaction between acetone and iodine, Mean reaction rate, Momentary reaction rate, Relative error
