Answer:
Explanation:
Hello
In this case, given the reaction:
It means that since the coefficients preceding phosphorous and phosphorous trifluoride are 1 and 4, the correct mole ratio should be:
Because given the mass of phosphorous it is convenient to convert it to moles and then cancel it out with the moles on bottom of the mole ratio.
Bes regards!
Answer:
Standard free-energy change at is
Explanation:
Oxidation:
Reduction:
--------------------------------------------------------------------------------------
Overall:
Standard cell potential,
So,
We know, standard free energy change at (
):
where, n is number of electron exchanged during cell reaction, 1F equal to 96500 C/mol
Here n = 2
So,
