Calculate the standard free-energy change for the following reaction at 25 °C. Standard reduction potentials can be found here.

Since there are no given data for us to solve this problem, I will explain what a Standard Reduction Potential is. For example, if a student had an experiment and he wanted to know what is the most efficient and powerful redox reaction involving an uncommon combination of chemicals. The student would most likely record information in the Standard Reduction Potential that showed the voltage generated by the reaction in Aqueous Solution at 25 degrees Celsius and 1 atmosphere. This is a list of half reaction of ions in the solution at standard temperature and pressure.
