Essential factors can affect the rate reaction. Three of these factors can be related to the rate constant of a reaction through an equation known as Arrhenius expression. First, state 4 factors that affect reaction rate. Next for EACH factor explain in one statement how EACH factor affect the rate of reaction at molecular level. Finally in no more than 2 sentences explain why the fourth factor is excluded form Arrhenius equation
