Answer 2

Ciao,
all those factors which change the number of effective collisions per second affect the rate of reaction.
1.nature of reactants.( the chemical reactivity of substances is controlled by electronic arrangement in their outermost orbitals. the elements of group 1A group have one electron in their outermost s.orbital. they react with water more swiftly than those of group 2A elements having two electrons in their outermost shell.
2.concentration of reacrants.( the frequency with which the molecules collide deoends upon their concentration. the mere crowded the molecule the more likely they are to collide with each other so rate of reaction increases.

3.surface area.( the increase in surface area increases the possibilities of atoms and molecules of reactants to come in contact with each other and thus rate enhances)
4.light.(light consist of photons having energy in them . this energy is provided to reactants thus rate increases.)
5. temprature.( temprature also increases tge energy of rectants so increases collision and rhus increasing reaction rate)
hope that you will find it helpful.
let me expalin how.
stay blessed☺
