To find a chemical reaction in which the change in enthalpy (ΔH) is equal to the change in internal energy (ΔU), we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Definitions**: - **Enthalpy (H)**: A measure of the total energy of a thermodynamic system, including internal energy and the energy required to make room for it by displacing its environment. - **Internal Energy (U)**: The total energy contained within a system, including kinetic and potential energy of the particles. ...
