Questions & Step-by-Step Solutions
Which of the following represents the enthalpy change for a reaction at constant pressure?
Step 1: Understand what enthalpy is. Enthalpy is a measure of the total energy of a system, including internal energy and the energy required to make room for it by displacing its environment.
Step 2: Recognize that reactions can occur at constant pressure, which is a common condition in many chemical reactions.
Step 3: Learn that the change in enthalpy during a reaction is called the enthalpy change.
Step 4: Identify the symbol used to represent enthalpy change. It is denoted by the Greek letter delta (Δ) followed by H, which stands for enthalpy.
Step 5: Conclude that the enthalpy change for a reaction at constant pressure is represented by ΔH.
