Thanks... I was confused a bit about finding 'n' in the Gibbs expression...

Saaame I was being a dumbass trying to add all the moles in the equation

You are now my master. I bow my head in respect.

This Teacher teaches EVERYTHING . Still doesn't care about changing the name of his channel.... Very nice to see that How passionate He is particularly with the "knowledge-spreading-mission " Name doesnt matter. We all know him as the " ORGANIC CHEMISTRY TUTOR "

Listening to this video is more useful than listening to my chemistry teacher ay school. This seriously help. Please keep making this kind of video.

thanks alot. you have no idea how helpful this is.

Wow I now know how to find n. Electrochemistry has never been simpler, all thanks to you. 😁

Thank you so much. you are now my master

i was taught to do it in a different way. LIke E overall = E reduction - E oxidation. Still got the same answer, but they way you did it relates exactly like adding up net reactions with their enthalpies. Which I had lots of practice with already, so it's simplier to do it your way since I'm already use to it. Thanks!

HEY PLEASE HOW DO I KNOW WHICH ONE TO REVERSE AMONGST THE TWO HALF EQUATIONS INCASE OF EXAMPLE 2?

@@Miss_Untichlobanty split the reaction into two half reactions. For the second example, once the two half reactions were written down, the Al one had switched sides, therefore you switch that one

Thank you for the great video!❣️ It helps a lot.

Thank you so much this really helped alot !!!🙏🏻❤️👍

Damn I am a international student studying in chinese medium. Just to understand the cell potentials connection with gibs energy I even saw 1 hr worth of helmholtzz free energy.... And finally I see organic chemistry has covered the topic I was looking for ;-;

Amazing .. thank you allote from saudi Arabia

This guy was sent by God 🙏🏾

Thank you Mr. Organic

What if the balanced equation ends up with a coefficient in front of the oxidized compound, which in turn changes the number of electrons transferred between the compound that is oxidized and the compound that is reduced? How many electrons would you use for the calculation in that instance?

As far as I know the cell potential doesn't depend on stoichiometric coefficients whereas Gibb's free energy change does.

God bless u bro🙏❤️

Thank You So Much Sir 🙏🙏

isnt delta g usually kj/MOL???

I’m just confused on why ,when we want to find E (not in standard conditions) we use delta G that’s in standard conditions or does it not matter that delta G is in standard conditions?

Your video made my day. :)

BEST TEACHER EVER~

And tomorrow, the problem they given to me are way harder

Thank you Soo much 💪

Smart solution

Thank you! ❤️

Thanks so very much

Thanks Bruhh !!!

good job

life saver

why are you adding both cells if equation is E=E (cathode)-E (anode)

@maheshkumar-fv9zn

Cause for oxidizing agent or e anode is negative quantity and a negative in front of negative gonna make it positive

@@Miss_Untichlobanty you actually need to reverse both of them in order to know how many electrons lost or gained. In ex 2, to balance the equation multiply missing number of electron if they are not balanced like Al has turned into Al3+ but Cu2+ has turned into just Cu So there's difference in number of electrons Multiply Cu by 3 Multiply Al by 2 You get 6 electrons Therefore n=6

Thanks

At 5.34 y are u inversing Al sir ,y not cu

?? why aren't you using the electrode potential equation ?? E of half cell where reduction occurs minus E of half cell where oxidation occurs

Can we calculate standard change in Gibbs free energy for the first reaction without knowing the standard cell potential?

@pameladiaz8307

You need to know the standard cell potential in order to calculate for the Gibbs free energy.

Thanks a lot

It's pronounced "coolum" not "kalloom"

Does the F vary , somewhere it is taken as 96500 ?????
