Considering the reaction: Zn(s) + Cu2+(aq) -> Cu(s) + Zn2+(aq) What is the cell potential (in volts) at 25°C when the concentrations of [Cu2+] and [Zn2+] are 0.5 M and 1.0 M, respectively, and the zinc electrode is the anode? The standard reduction potentials for Cu2+/Cu and Zn2+/Zn are 0.34 V and -0.76 V, respectively.

Calculate the current density in an electrochemical cell if a current of 2.5 A is passed through a copper electrode with a surface area of 25 cm² and a silver electrode with a surface area of 10 cm² for 3 hours. The half-cell potentials of copper and silver electrodes are +0.34 V and +0.80 V, respectively, and the molar concentrations of copper and silver ions in the electrolyte are 0.5 M and 1 M, respectively.

A chemical engineering firm has been tasked with designing a chemical reactor for the synthesis of ammonia gas from nitrogen and hydrogen gases. The plant requires a production of at least 1000 kg/h of ammonia gas, and the reactor should operate at a pressure of 200 atm and a temperature of 400°C. The student should determine the optimal size and design of the reactor by considering the reaction kinetics, thermodynamics, and fluid dynamics principles. The student should also select appropriate catalysts and determine the flow rate of the reactants required to achieve the desired production rate.
