Problem
An industrial decomposition of X₂O₃(s) produces O₂(g). The process now runs at 600 °C with an average solid particle diameter of 2 mm and reactant partial pressure of 1.0 atm. The catalyst supply is exhausted, so no additional catalyst can be added. Management wants the rate of O₂ production doubled using the least expensive operational change. Which proposal best meets the goal?
(a) Increase the furnace temperature to 650 °C while keeping all other variables unchanged.
(b) Raise the reactant partial pressure to 1.5 atm and reduce the particle diameter to 1.5 mm.
(c) Grind the solid so the average particle diameter is reduced from 2 mm to 1 mm, leaving temperature and pressure unchanged.
(d) Increase the furnace temperature to 620 °C and reduce the particle diameter to 1.5 mm.
