Which species does the first transition state of the overall reaction most ressemble? What kind of transition state is this (late or early)?

Draw a possible transition state for the bimolecular reactiondepicted here. (The blue spheres are nitrogen atoms,and the red ones are oxygen atoms.) Use dashed lines torepresent the bonds that are in the process of being brokenor made in the transition state.

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.

Reactions involving strong acids like HCl or strong bases like NaOH these tend to be very exothermic. Draw a reaction coordinate diagram for these reactions. Label the reaction coordinate diagram by indicating the reactant, the intermediate, the transition states and the product

Use the energy diagram for the reaction A D to answer the questions. How many transition states are there in the reaction? transition states: How many intermediates are there in the reaction? D Reaction progress intermediates: Which step of the reaction is the fastest? Which step of the reaction has the smallest rate constant? Assume the frequency factor (A) is the same for for each elementary reaction. Is the overall reaction exothermic or endothermic? O exothermic O cannot determine from the diagram O endothermic Potential energy

Which of the following statements is false? Free Energy Reaction Progress O the reaction is endothermic OThe equilibrium for this reaction favors the products the second step is the rate-determining step the point X is consistent with the transition state for the second step

15. Which statement below best describes the difference between an intermediate and a transition state? A)  Anintermediatecannotbeisolatedwhileatransitionstatecan. B)  Atransitionstateisalwayshigherenergythanthereactantswhile intermediates are always lower energy than the reactants. C)  A transition state does not persist while an intermediate has a defined lifetime. D)  Anintermediateisalwayshigherenergythanatransitionstate. E)  None of these statements are true.

A hypothetical reaction is shown with the reaction coordinate diagram. How many steps are in the reaction mechanism? VI Reaction Progress O6
