Questions & Step-by-Step Solutions
Which of the following factors does NOT affect the enthalpy change of a reaction?
Step 1: Understand what enthalpy change means. It is the heat content change during a chemical reaction.
Step 2: Learn that enthalpy is a state function. This means it depends only on the initial and final states of the system, not on how the reaction occurs.
Step 3: Identify factors that typically affect reactions, such as temperature, pressure, and concentration.
Step 4: Recognize that since enthalpy is a state function, the specific pathway or method of the reaction does not affect the overall enthalpy change.
Step 5: Conclude that the factor that does NOT affect the enthalpy change is the pathway taken during the reaction.
