Units G=-nFE Postby 805312064 » Fri Mar 06, 2020 4:17 pm I'm not sure if this is common sense, but if the units for F are coulombs and the units for E are volts, how do we get joules for G?

2016年3月28日 · Hey all, I was reviewing one of my missed destroyer questions (#158 in the 2015 Destroyer), and it was to calculate ∆G. From what I understand, n is the number of moles of electrons. The problem gave the reduction and oxidation reaction: one had 3 electrons transferred, the other had 2...

2020年3月9日 · G=-nFe Postby Jasleen Kahlon » Mon Mar 09, 2020 6:30 am I know that in the G=-nFe equation, n is the number of electrons transferred. Does that mean the electrons transferred from 1 compound to another? I'm confused because in a lot of equations, everything rearranges from one side to the other...

2020年2月26日 · Re: delta G = -nFE Postby Brianna Becerra 1B » Wed Feb 26, 2020 6:16 am If a process is spontaneous, then E is a positive value. Due to the set up of the equation, this also means that if a process is spontaneous, then delta G is equal to a negative value. Both of these rules apply with the negative symbol applied to the equation.

2019年2月24日 · Re: Finding n in Delta G = -nFE Postby Andrew Bennecke » Mon Feb 25, 2019 6:16 am This is the value of moles of electrons that cancel in each of the half reactions before writing the whole net ionic equation.

2020年3月1日 · Re: Units for delta G Postby VPatankar_2L » Sun Mar 01, 2020 7:16 am Since one Faraday is 96485 C/mol, it can be multiplied by n (moles) in the equation delta G = -nFE to just get kJ.

2020年3月9日 · In dG = -nFE, F represents the ratio between charge and one mole of electron, and E represents voltage. As a logical continuation of this, n would thus need to represent the mole of ELECTRONS.

2015年2月4日 · I am confused with the derivation of the nernst equation. My book gives this 1. If we start with G = Go + RT lnQ and sub in -nFE for G, where is the z (instead of n coming from in the equation? 2. What happens to Eo at the end? 3. I know that Q is Products/Reactants. I am confused with how...

2022年2月21日 · Re: n in ∆G = -nFE by Sunny Wu 3A » Sun Feb 28, 2021 12:21 am Like Will said above, n is the number of moles of electrons being transferred (and not moles of reaction like in previous units). To find n, split your overall chemical reaction into an oxidation half reaction and a reduction half reaction.

2020年3月4日 · G=-nFE equation Postby Alicia Lin 2F » Wed Mar 04, 2020 1:23 am does the equation G=-nFE still apply to nonstandard values? It only specifies the standard values on the equation sheet.
