What are the values of ∆G° and ∆E° for a spontaneous reaction

Answer 1

The values of ∆G° and ∆E° for a spontaneous reaction are as follows:

1. ∆G° (Gibbs Free Energy Change): For a spontaneous reaction, the value of ∆G° is negative, meaning the reaction releases energy and occurs spontaneously.

2. ∆E° (Standard Cell Potential; only applicable for electrochemical reactions): For a spontaneous electrochemical reaction, such as in a galvanic or voltaic cell, the value of ∆E° is positive, meaning there is a release of electrical energy.

Note that these conditions are applicable for spontaneous reactions under standard conditions (1 bar pressure, 298 K temperature, and 1 M concentration).
