A reaction Gibbs energy, ΔG, is sometimes not easy to determine experimentally. However, if the chemical reaction is a redox reaction that can be assembled into the form of a voltaic cell, then the Gibbs energy, ΔG, can be measured using just a volt meter! Consider the following redox reaction: 2 NO3− + 8 H+ + 3 Cu → 2 NO + 4 H2O + 3 Cu2+ It is a complicated reaction! You should be happy that you donate need to understand but in order to answer this question. Although it is complicated looking, it can be setup as a voltaic cell, where the voltage, Ecell, is measured to be +0.62 V on a voltmeter. What is the Gibbs energy of the redox reaction above as written, in kJ (to 1 decimal place)? You also need to know that there are 6 electrons involved in this reaction. Use the following to determine ΔG. ΔG = -n F Ecell F = 96,485 Coulombs/mol
