select all the correct answers. which changes will increase the rate of reaction during combustion? decreasing the area of contact between the reactants adding more oxygen to the reaction removing heat from the reaction changing the reactants from solid form to powdered form lowering the exposure of the reactants to air

select all the correct answers. which changes will increase the rate of reaction during combustion? decreasing the area of contact between the reactants adding more oxygen to the reaction removing heat from the reaction changing the reactants from solid form to powdered form lowering the exposure of the reactants to air

Answer

Brief Explanations:

  • Decreasing contact area slows reaction.
  • Adding oxygen (reactant) speeds it up.
  • Removing heat reduces reaction rate.
  • Powdered form increases surface - area, speeding reaction.
  • Lowering air - exposure slows reaction.

Answer:

B. adding more oxygen to the reaction D. changing the reactants from solid form to powdered form
