3. (a) Yield is the maximum amount of product which can be expected from a reaction based on many parameters taking place in the system. Can thermodynamics help the process engineer to determine the maximum yield of a specified product in a chemical reaction. Justify with examples? [15 marks] (b) Maxwell equations are thermodynamical equations which are highly helpful in replacing unmeasurable quantities appearing in thermodynamic equations by measurable quantities. Enumerate the applications of Maxwell equations in process Industries. [10 marks]
