Calculate the standard electrode potential for a redox reaction involving the reaction of iron (Fe) with copper (Cu) ions, given the following half-reactions: Fe2+ + 2e- → FeCu2+ + 2e- → Cu (Note: The standard electrode potential values for Cu2+/Cu and Fe2+/Fe half-cells at 25°C are 0.34V and -0.44V, respectively.)

Design a heat exchanger to cool down a mixture of water and ethylene glycol from 80°C to 20°C using cooling water from a nearby lake that enters at 15°C. The mixture flow rate is 10 L/min, and the desired outlet temperature is 20°C. The heat transfer coefficient for the heat exchanger is 250 W/(m².K) and the overall heat transfer coefficient is to be assumed as 350 W/(m².K). The heat capacity of the mixture is 3.8 kJ/(kg.K) and the density is 1030 kg/m³. Determine: a) the surface area of the heat exchanger required for this process,b) the volume flow rate of cooling water required, and c) the overall heat transfer rate in kW.
