Review I Constants Periodic TableFor a reaction to occur, bonds must be broken and/or made. This process includes a high-energy transition state. Formation of this transition state is energetically unfavorable. Thedifference in energy between the reactants and the transition state is called the activation energy. Catalysts can accelerate the chemical reaction by providing a lower energy pathwaybetween the reactants and the products. This usually involves the formation of a transition state or an intermediate that cannot be formed without the catalyst. The catalyzed reactionpathway generally has a much lower activation energy barrier than is required for the direct reaction of reactants to products. Notice what catalysts do not do: They do not change theenergy of the reactants, products, or overall reaction. What changes is the activation energy.No catalystWith catalystEadNa cataivstEac+ catalvstReactantsEnergyProductsProgress of reaction >The collision theory of reactions states that, for a reaction to occur, molecules must collide with sufficient energy and the proper orientation. A catalyst can increase the rate of reaction byincreasing the probability of the molecules colliding with the correct orientation. Increasing the temperature can also increase the rate of a reaction, as it increases both the energy of themolecules and the number of collisions between molecules.The connection among the rate of the reaction, temperature, and activation energy is given by the Arrhenius equation: k = Ae Ba/RI where k is the rate constant for the reaction rate,Ea is the activation energy, R is the gas constant, equal to 8.314 J/(mol K), T is the temperature in kelvins, and A is the pre-exponential constant for the reaction. The pre-exponential constant has the same units as k.Part ABy what factor does increasing the temperature of a reaction from T = 273 K to T, = 283 K increase the rate of reaction?

True or False 1. It is imperative that collision occurs between two reactant particles to proceed with the reaction.2. A lower energy of activation means that fewer molecules will have sufficient energy to undergo an effective collision.3. If a reaction has a low rate, it means that the molecules combine at a slower speed than a reaction with high rate.4. When pressure is increased, the rate of reaction between gas particles will decrease.5. Chemical catalysts experience change when they speed up rates of reactions.6. An increase in temperature generally decreases the activation energy.
When the concentration of reactant molecules is increased, the rate of reaction increases. The best explanation is: As the reactant concentration increases, the rate constant increases. the activation energy increases. the frequency of molecular collisions increases. the order of reaction increases. the average kinetic energy of molecules increases.

It is INCORRECT to affirm that: The overall reaction may either release energy or absorb energy. Exergonic reactions (ex- = out) release more energy than they absorb. The overall reaction may either release energy or absorb energy. Endergonic reactions (end- = within) absorb more energy than they release. Energy released from an exergonic reaction often is not used to drive an endergonic one. The collision energy needed to break the chemical bonds of the reactants is called the activation energy of the reaction.
