Front (Question)
Contact process 2SO2 + O2 -> 2SO3 (reversible reaction) - company wants to increase pressure and temperature - Delta H = -197 Evaluate feasibility of each of these changes in terms of their effect on the rate, yield and economics of the reaction (6)
Back (Answer)
• Increase in temperature increases rate of reaction • Equilibrium shifts left to favour endothermic reaction, decreases yield • Increase ENERGY costs • Increase in pressure increase rate of reaction • Equilibrium shifts right to favour reaction which produces least moles • Increased pressure increases construction and running costs
