Kf units Electrolytic Cell Volt Regression

This document outlines the equations used to calculate standard volts for electrolysis processes. It provides the input variables like catholyte concentration and temperature and explains the calculation steps. It highlights that some constants are process dependent or related to thermodynamic limitations. Two methods are described for predicting volts at a given current density: the Kf method which uses a slope between volts and current density, and the Unitary method which uses the average actual volts.
