To determine the standard molar enthalpy of formation of carbon dioxide (CO₂), we can follow these steps: ### Step 1: Understand the Definition The standard molar enthalpy of formation (ΔH_f°) of a compound is defined as the change in enthalpy when one mole of the compound is formed from its elements in their standard states. ### Step 2: Identify the Elements and Their Standard States For carbon dioxide (CO₂), the elements involved are carbon (C) and oxygen (O). The standard state of carbon is graphite (C), and the standard state of oxygen is O₂ gas. ...
