Interpretation Introduction

Interpretation:

The value of “ $x$ ” and “ $y$ ”in the reaction $2A^{x+}+3B\to 2A+3B^{y+}$ is to be calculated.

Introduction:

The cell potential of a certain electrochemical cell states how much voltage generates between two half cells of that electrochemical cell. We can denote the cell potential using $E^0$. On the other hand, the free energy change or $\Delta G^0$ is a thermodynamic quantity that describes the internal energy of the electrochemical cell which is available to generate electricity. There is a relationship between cell potential and free energy change as follows:

$\Delta G^0=-nF{E}^0$

Where, $n$ is the number of moles of electrons that transfer during the reaction while $F$ is the Faraday Constant.
