Questions & Step-by-Step Solutions
Which of the following has the highest enthalpy of formation?
Step 1: Understand what enthalpy of formation means. It is the energy change when one mole of a compound is formed from its elements in their standard states.
Step 2: Identify the compounds or elements you are comparing for their enthalpy of formation.
Step 3: Look up the enthalpy of formation values for each compound or element. These values are usually found in tables in chemistry textbooks or online.
Step 4: Compare the enthalpy of formation values. The one with the highest value is the compound that has the highest enthalpy of formation.
Step 5: Conclude that CO2(g) has a higher enthalpy of formation compared to the elements in their standard states.
