Text Solution

AI Generated Solution

To determine what happens to the equilibrium constant of an exothermic reaction when the temperature is increased, we can follow these steps: ### Step 1: Understand Exothermic Reactions Exothermic reactions are those that release heat. In a chemical equation, they can be represented as: \[ \text{Reactants} \rightleftharpoons \text{Products} + \text{Heat} \] ### Step 2: Apply Le Chatelier's Principle Le Chatelier's Principle states that if an external change is applied to a system at equilibrium, the system will adjust itself to counteract that change and restore a new equilibrium. ...
