Electromotive Force and Gibb’s Free Energy Chemistry Notes
E.m.f. and Gibb’s Free Energy :
→ In Daniell cell, chemical energy is converted into electric energy. This electric energy is used in different electric works. So, electric energy can be converted into work quantitatively, Here, electric energy, which is produced by cell, can be represented by following equation :
Free energy (AG) in a process is equal to work done by it at constant temperature and pressure. So,
