Question

Calculate the standard free-energy change for the following reaction at 25 °C. Standard reduction potentials can be found here.
2Au(3+) + 3Cr-->2Au+3Cr(2+)

Answer 1

Janu, Ladoo, et al. It helps us help you better if you use the same screen name.
Look up the potentials, add the oxidation half to the reduction half to obtain Eocell. Then dG = -nFE

Answer 2

^Those are my friends they are different people with the same question

Answer 3

Then you must be in the same room using the same computer so just talk to each other; you don't need to talk via computer.
