If the activation energy of a reaction increases, what happens to the rate constant (k)? A.the rate constant decreases B.the rate constant stays the same C. there isn't enough information to predict what happens to the rate constant D. the rate constant increases
Increasing the temperature of the reactants increases the fraction of the reacting species that collide with energies equal to or greater than the free energy/activation energy. Another factor that can affect whether or not molecules react is their orientation/bond length toward one another when they collide. Molecules with incorrect bond lengths/orientations will not react even if they successfully collide.
po Energy and Matter Transition States At the peak of the Reaction Pathways graph, there is a brief interval between the time that the reactant bonds are broken and product bonds are formed. This transitional structure is called an activated complex, and it exists for only a brief period of time. Just because the activated complex forms does not necessarily mean products will form. It may return to the original reactants, Increasing the temperature of the reaction causes more particles to have sufficient energy to form the activated complex on collision. That is why reaction rate increases as temperature increases. Increasing temperature increases the opportunities for products to form.
