Input: Consider Input: Question: The Nernst equation: 
 Options:  <1> It is true both for reversible and highly irreversible galvanic cells. <2> It allows to calculate the electromotive force of a galvanic cell with only knowing the Gibbs energy standard of the chemical reaction of the cell. <3> It depends solely on the activities of the species that participate in the chemical reaction of the cell. <4> It relates the electromotive force of the cell with the activities of the species that participate in the chemical reaction of the cell and with the standard potential of the reaction. <5> It is independent of the number of electrons transferred in the electrochemical reaction of the cell

Output: 4
