I have written down all the information we're given in this problem, and we are asked to find gives free energy in kilojoules, and k would be, and we're asked to choose than one, and i'm sure it's greater than equal to or less than one.
00:29
Okay, so let's get started.
00:33
In order to do this, our first order of business will be to calculate our, for the cell, which will equal r, e for my reduction, minus e for my oxidation.
01:06
And my reduction will be, you can see that this one's being reduced.
01:12
So i'm going to have my 10, negative 0 .140 volts minus negative 0 .280 volts.
01:26
And that's going to equal negative 0 .14.
01:35
It'll be plus .28.
01:37
This will be positive 0 .140 volts.
01:45
So let's go ahead and make this a...
01:57
What did they ask me? oh, that's not what i need right there...
