Questions & Step-by-Step Solutions

What is the primary factor affecting the rate of a surface reaction?
  • Step 1: Understand that a surface reaction occurs at the interface between two phases, like solid and gas or solid and liquid.
  • Step 2: Recognize that the more surface area available for the reactants, the more places there are for the reaction to occur.
  • Step 3: Realize that if you increase the surface area (for example, by grinding a solid into a powder), the reaction can happen faster.
  • Step 4: Conclude that the primary factor affecting the rate of a surface reaction is the surface area of the reactants.
