B) surface area is the answer

Hope its help...

Answer 2

Answer:

Exposing more particles for collisions is a rise in surface area.

Explanation:

• Collision theory states that a chemical action can only happen if two reactant particles run into enough energy to beat the energy barrier.
• The reaction rate are quite low if collisions aren't happening particularly often or if the energy of the collisions is below the energy of activation barrier.
• Collision theory will be wont to understand how temperature affects the reaction rate.
• Higher temperatures make reactant particles move around quickly and with plenty of energy.
• Particles that move faster and with more energy have more frequent and more energetic collisions.
• The reaction rate will increase if the temperature is increased because the reactant particles collide more frequently and with more energy; the reactant particles overcome the energy of activation barrier more often and therefore the reactant particles transform into product particles at a faster rate.
