With increase in temperature, the equilibrium constant at constant pressure (Kp) for oxidation of sulphur dioxide________________?
Correct answer: C. Decreases
- A. Increases
- B. Increases linearly
- C. Decreases
- D. Decreases linearly
Explanation
Oxidation of SO2 to SO3 is exothermic, so increasing temperature shifts equilibrium toward the reactants. Consequently, Kp decreases with temperature, although not necessarily linearly.
