Alright, so we're given the half reaction of an electrochemical cell, the anode and the cathode.
00:09
And then we actually use the reduction potential chart to calculate the standard cell potential for that electrochemical cell.
00:17
Well, the e cell standard would be the e theta of the cathode minus the e theta of the anode.
00:29
So, and we already told that the chromium half cell is the cathode, sorry is the anode and the bromine half cell is the cathode.
00:39
And we can see the e theta values given to us.
00:42
There's that.
00:44
And you have to be very careful.
00:45
This is chromium three.
00:47
So that's this, right? chromium three to chromium.
00:53
That's what you can see that that equation.
00:55
Chromium goes from zero to plus three...
