bonds to be broken. The activation energy, Ea, of the forward reaction is the difference between the energy of the products and the energy of the transition state. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes more slowly. If the heat of reaction, AH, is negative, the energy of the products is higher than the energy of the reactants and the reaction is exothermic. When the activation energy is high, the reaction rate is fast. Increasing the concentration of reactants increases the number of collisions, and the reaction goes faster. Reactants must collide with proper orientation and with energy greater than or equal to the activation energy for a reaction to occur.

(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. As a reaction progresses its rate goes down. The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step. Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities. Reaction rates increase with increasing temperature. Reactions involving very unstable combinations of chemicals have large rate constants.
