A chemistry student needs to determine how the equilibrium concentration of products and reactants change when the temperature is increased in the reaction: 2 SO2 (g) + O2 (g) ⇌ 2 SO3 (g) Given the initial concentrations of 0.15 M SO2, 0.025 M O2, and 0 M SO3, and a temperature increase of 50°C, calculate the new equilibrium concentration of each compound using Le Chatelier's Principle.

A chemical mixture containing 30% ethanol and 70% water needs to be separated using a distillation column. The feed rate is 1000 kg/hr and the desired purity for both products is 99%. The distillation column has 20 theoretical trays, and the reflux ratio is 2.5. Determine the number of trays required to achieve the desired purity for both products.
