根据酸催化原理，利用自行设计的装置，测定了酸催化甲酸分解生成一氧化碳的模拟反应的速度常数ＫＭ．理论分析与实测结果表明，ＫＭ值反映了酸的催化活性的大小，可作为制备或选用新的催化剂的参考依据
According to the principle of acid catalysis, the rate constant KM of simulated reaction of acid catalyzed formic acid decomposition to carbon monoxide was determined by a self-designed device. Theoretical analysis and experimental results show that the KM value reflects the size of the catalytic activity of the acid and can be used as a reference for the preparation or selection of a new catalyst
