What happens on the molecular level when you increase the reactants' surface area?

Question

*
more surface area means there are fewer possible collisions between reactants
the reactant particles' speed increases so there are more collisions and increase force
the hotter the system is, the better the molecules can hold their orientation
having the reactant in smaller pieces means there are more surfaces for the reaction to take place

Answer 1

increasing the surface area of the reactants allows for more opportunities for collisions to occur between particles, leading to a higher likelihood of successful collisions and faster reaction rates. This is due to the increased number of exposed reactant molecules available for interaction with other molecules. The smaller pieces of reactants also provide more surface area for the reaction to take place, allowing for more efficient and quicker reactions. Additionally, the increased surface area can lead to more effective mixing and distribution of reactants, further promoting the speed of the reaction.
