如何使用cv計算速率常數(shù)?
已知物質(zhì)A發(fā)生EC反應(yīng),電極反應(yīng)可逆,化學(xué)反應(yīng)不可逆。
主要是不太明白如何將速率方程和掃描速率結(jié)合在一起。(實際是一道考試題……看了很多資料都沒搞懂,老師不提供答案)謝謝大佬解答!

For a reversible reaction, ip∝ v^1/2,since the electrode reaction is reversible while the fragmentation reaction is irreversible, the different between cathodic peak current density icp and anodic peak current density iap should be responsible for the a-* consumption, then you can determine k
Sorry the computer in the campus dont provide chinese input method... Really thank you for the explanation. I now figure out how the rate constate relates to the current density but still feel confused about the function of the halfwave potential during a CV exp. Could you please help or suggest a book or an article? Thank you

《Electrochemical Methods Fundamentals and applications》 by Allen J. Bard, this book is really classic
