例句与用法
- 6 ) , the process that h20 is adsorbed on the electrode surface and the hydroxyl group is formed to oxidize the co may be the rate - determining step ; in the region iil ( logi > l . 6 ) , all of the tafel curves show a curvature until the current densities reach the peak value , indicative of a possible limiting current . the effect of rare earth elements on methanol electro - oxidation has not been reported in literatures
在低极化区( logi 1 . 3 ) ，甲醇发生脱氢反应并形成反应中间体，其中co成为未被氧化的毒物，此过程成为速率限制步骤；在更高的极化区( 1 . 3 logi 1 . 6 ) ， h _ 2o吸附在电极表面并解离生成[ oh ] ，促进了co的氧化，此为此阶段速率控制步骤：在第3个极化区( 10gi 1 . 6 ) ， tafel曲线发生弯曲，电流密度也最终达到峰值。
百科释义
In chemical kinetics, the rate (or velocity) of a reaction mechanism with several steps is often determined by the slowest step, known as the rate-determining step (RDS) or rate-limiting step. The experimental rate equation can help to identify which step is rate-determining.
