Question
Consider the following equation: 2SO4(g) + O2(g) → 2SO3(g), H = –190 kJ The number of factors which will increase the yield of SO3 at equilibrium from the following is ________. A. Increasing temperature B. Increasing pressure C. Adding more SO2 D. Adding more O2 E. Addition of catalyst
💡 Solution & Explanation
(i) As reaction is exothermic. So on increase in temperature equilibrium shift in backward direction. (ii) On increasing pressure equilibrium shift in forward direction. (iii) Addition of catalyst does not affect equilibrium it only increase rate of reaction. (iv) Addition of catalyst does not affect equilibrium it only increase rate of reaction.
