The standard free energy change for a reaction is -212.3 kJ mol -1.
If the enthalpy of the reaction is - 216.7 kJ mol-1, calculate the entropy change for the reaction.
The device through which chemical energy is converted into electrical energy is known as galvanic cell or electrochemical cell or voltaic cell. In a galvanic cell, a redox reaction
