Questions & Step-by-Step Solutions

In the Arrhenius equation, what does the term 'A' represent?
  • Step 1: Understand that the Arrhenius equation is used to describe how temperature affects the rate of a chemical reaction.
  • Step 2: The Arrhenius equation is usually written as k = A * e^(-Ea/(RT)), where k is the rate constant.
  • Step 3: In this equation, 'A' is a term that helps us understand how often reactants collide with each other.
  • Step 4: 'A' is called the frequency factor, and it represents the number of successful collisions that can lead to a reaction.
  • Step 5: A higher 'A' value means more collisions are happening, which can lead to a faster reaction rate.
