Calculate the enthalpy change for the reduction of iron (III) oxide using carbon in a thermite reaction if 12.5 grams of iron (III) oxide reacts with excess carbon, and the resulting iron has a mass of 7.5 grams. Assume all heat evolved is absorbed by the iron and that the reaction occurs at constant pressure.

A student is studying the electrochemical reaction of the metal copper in acidic solution. They measure the current density at different applied potentials and obtain the following data:Potential vs. SHE (V) | Current Density (mA/cm²)---|---0.0 | 0.00.1 | 0.50.2 | 2.00.3 | 5.00.4 | 11.0Using this data, calculate the anodic and cathodic Tafel slopes, and determine the rate constant for the electrochemical reaction.
