Lesson: The Contact Process Chemistry
In this lesson, we will learn how to describe the production of sulfuric acid in the contact process and explain the choices of reaction conditions.
When sulfur dioxide reacts with oxygen gas to form sulfur trioxide, energy is absorbed when bonds are broken and released when bonds are formed. The bonds in sulfur dioxide have an energy of 522 kJ/mol, while those in sulfur trioxide have an energy of 495 kJ/mol. The double bond in oxygen has an energy of 494 kJ/mol. Determine whether the reaction is endothermic or exothermic and calculate the total energy change per mole of sulfur dioxide.
