Questions & Step-by-Step Solutions
What does the term 'enthalpy of formation' refer to?
Step 1: Understand that 'enthalpy' is a measure of energy in a system.
Step 2: Know that 'formation' means creating something.
Step 3: Realize that 'enthalpy of formation' specifically refers to the energy change when a compound is made.
Step 4: Remember that this process involves one mole of the compound.
Step 5: Recognize that the elements used to form the compound must be in their 'standard states', which means they are in their most stable form at a specific temperature and pressure.
