Which of the following statements is TRUE? Select one: O Increasing the temperature will speed up the rate of reaction by altering the reaction mechanism. Adding a catalyst will speed up the rate of reaction by providing the reactant molecules with more energy. An elementary step has one intermediate. After 2 half-lives, the reactant concentration drops to 1/4 the initial concentration. The larger the activation energy, the faster the reaction rate.

Typical Chemical Potential Energy (PE) Diagram for an Exothermic Reaction A catalyst provides an alternate pathway for a reaction to occur. The alternate pathway has a lower activation energy (AE), meaning that the reactant molecules do not need to collide with as much energy in order for a reaction to occur, so more collisions result in a reaction, so the reaction rate is faster. Chemical Potential Energy (Enthalpy) Note that adding a catalyst does not change the amount of energy released (AH) for the reaction.
