Which of the following methods for increasing the rate of chemical reaction increases the effectiveness of the interactions betw
een reactants, instead of just causing the reactant molecules to bump into each other more frequently Increasing the temperature of the reactants
Increasing the surface area of the reactants
Adding a catalyst to the reactants
Increasing the concentration of the reactants
An increase in surface area of the reactant will always cause an increase in the rate of reaction. This is so because, an increase in the surface area of the reactant will cause the reactant particles to collide effectively thereby bringing about an increase in the reaction rate.
Collision theory suggests that for a reaction to occur, the reactant particles must collide with the right orientation. As the surface area of the reactants are increased, the reactants particles collide more with the right orientation bringing about definite increase in the rate of reaction.

Water moves through the help of living organisms in an ecosystem. ... Plants absorbs water through their root system and loss by transpiration. Water also moves through the living organisms in an ecosystem. Other nonliving processes such as evaporation, precipitation, water returns back into the atmosphere.
