A copper rod with a surface area of 5 cm² is coupled with an iron rod with a surface area of 10 cm² to form a galvanic cell. When the circuit is closed, the current flows for 2 hours and the weight loss of the iron rod was found to be 0.58 g. Determine the corrosion rate of the iron rod in millimeters per year (mm/yr) assuming a density of 7.86 g/cm³ for the iron.

A chemistry student is asked to determine the concentration of a particular compound in a sample of drinking water. The student collects a 100 mL water sample and adds a known amount of a standard solution containing the compound. After allowing the solution to equilibrate, the student measures the concentration of the compound in the new solution using a spectrophotometer, to be 0.0125 M. Assuming mass balance, calculate the concentration of the compound in the original drinking water sample.

A 0.50 L vessel contains 1.0 mol of N2(g) and 3.0 mol of H2(g) at equilibrium at 400 K according to the following equation:N2(g) + 3H2(g) ⇌ 2NH3(g)If the volume of the vessel is suddenly decreased to 0.25 L, what will happen to the equilibrium position? Will the concentration of NH3 increase or decrease? Calculate the new equilibrium constant at this new volume.

A chemistry student is studying the adsorption of a gas on a solid surface using the Langmuir adsorption isotherm. The student knows that the maximum adsorption capacity (θ_max) of the surface is 0.5 mol/L and that the equilibrium constant (K) for the process is 0.02 L/mol. The student is asked to calculate the fraction of the surface covered by the adsorbate when the gas pressure is 2 atm at the temperature of the experiment.

A steel pipe is in contact with a copper pipe in a galvanic couple, with the steel pipe acting as the anode. The corrosion current density of the steel pipe in the couple is 0.008 mA/cm². Determine the rate of corrosion of the steel pipe, assuming that the density of steel is 7.8 g/cm³ and the thickness of the pipe is 2.5 mm. Also, calculate the time taken for the pipe to corrode completely, assuming an initial mass of 5 kg.
