Homework Answers
I think all options are correct because any change in concentration of reactants will have some effect on the reaction rate. Also, change in temperature ( increase of decrease) will increase or decrease the reaction rate.
Changing the particle size means change in surface area, more the area, more faster will be the reaction.
