• how does logK appear after you multiply by the ln10 what is the rule?
• He did a very poor job explaining. He does nt show that he multiplies and divides the right side by ln10.

E0=((.0257ln10)/n)(lnk/ln10)

lnk/ln10= logk by change of base rule. substitute and you get what he got
• , did he make a mistake?

0.0257 X log 10 = 0.0257

Edit: Yeah, he did, just used calculator and log 10 is 1.

Edit 2: Nope, he didn't, so basically here is what happened. To convert Ln to Log 10, you have to times it by 2.303. Instead of showing the whole conversion, he made a mistake and did 0.0257 X log 10 = 0.0257.

So it should have been as follow:

0.0257 X 2.303 (ln to log 10) = 0.0592

then

E = (0.0592 / n) x Log K
