create a hypothesis
As more and more molecules are available to react, do you predict the reaction to speed up or slow down? Is this unlimited? Do you predict the reaction fully consumes the reactants or will there always be some unreacted material? Does concentration change how fully the reactants are consumed?
Based on the collision theory of chemical reactions, I hypothesize that as the concentration of reactants increases, the reaction rate will also increase. This is because with more molecules present, there is a higher probability of successful collisions leading to product formation. However, I do not believe that there is an unlimited increase in reaction rate with increasing concentration, as there may eventually be a point where all active sites on the reacting molecules are occupied.
I predict that the reaction will not fully consume all of the reactants, as there may be factors such as equilibrium reactions or inhibitory processes that prevent complete consumption. I also hypothesize that higher concentrations of reactants will lead to a greater degree of consumption, as there are more molecules available to participate in the reaction.
