Identify which of the following factors would most likely cause the rate of a chemical reaction to slow.
Increase in concentration of reactants
Increase in surface area of reactants
Increase in temperature of reactants
Increase in volume of reactants
A catalyst is used to increase the rate of a reaction, briefly explain how this occurs.
It decreases the amount of energy required for the reaction to occur
It offers an alternative path for reactants to take.
It helps increase the likelihood that reactants will collide with enough energy and proper position.
