  3. Increases the rate
  4. Only affects gas-phase reactions

Questions & Step-by-Step Solutions

What is the effect of increasing the surface area of a solid reactant on the reaction rate?
  • Step 1: Understand that a reaction occurs when particles collide with each other.
  • Step 2: Recognize that solid reactants have a limited area where these collisions can happen.
  • Step 3: Realize that increasing the surface area means breaking the solid into smaller pieces or powders.
  • Step 4: Know that more surface area allows more particles to be exposed and available for collisions.
  • Step 5: Conclude that with more collisions happening, the reaction rate increases.
