Redox Reaction Calculator

How to Use the Redox Reaction Calculator

The Redox Reaction Calculator is designed to evaluate the changes involved in a redox reaction by inputting various parameters. Follow the steps below to use this tool effectively.

Step 1: Select the Type of Redox Reaction

Begin by selecting the Type of Redox Reaction you want to analyze. You have two options available:

• Oxidation Number Change: Select this option if you wish to analyze based on the change in oxidation states.
• Electron Transfer: Choose this if you’re focusing on the actual number of electrons exchanged during the reaction.

Step 2: Enter the Initial and Final Oxidation States

In the next fields, input the Initial Oxidation State and the Final Oxidation State of the element involved in the redox process. These should be integers ranging from -7 to 7. Ensure each is filled accurately to calculate the change correctly.

Step 3: Input the Number of Moles

Enter the Number of Moles participating in the reaction within the range of 0.001 to 1000. Accurate input is crucial, as this value is used for multiple calculations, including electrons transferred and Gibbs free energy change.

Step 4: Set the Temperature

Specify the Temperature (K) under which the reaction occurs. The input can range between 0 and 10,000 Kelvin. This value is used to compute the Gibbs free energy change, so ensure it matches your reaction conditions.

Understanding the Calculated Results

• Change in Oxidation Number: This value is derived from the difference between the final and initial oxidation states, displayed as an integer.
• Number of Electrons Transferred: Calculated as the absolute change in oxidation number multiplied by the number of moles, presented to three decimal places, in moles of electrons.
• Reaction Classification: The calculator will classify the reaction as either Oxidation or Reduction based on the oxidation states.
• Total Charge Transfer: This is the total charge calculated in Coulombs using Faraday’s constant, formatted to two decimal places.
• Gibbs Free Energy Change: Represents the energy change in kilojoules per mole, considering temperature and charge transfer, formatted to two decimals.
