Draw a reaction-energy diagram for a one-step exothermic reaction. Label the parts that represent the reactants, products, transition state, activation energy, and heat of reaction

The first graph below represents the energy level diagram for an uncatalyzed reaction. Which other graph could represent the same reaction but catalyzed?

Identify the energy diagram(s) that illustrate a slow reaction. Select all that apply. Ea Ea AH AHP Reaction coordinate Reaction coordinate Ea AH AH Reaction coordinate Reaction coordinate Energy Energy Energy

Products Reactants Extent of reaction Which letter shows the non-catalyized reaction? Energy

2. Select the energy profile templates below (A or B) that correctly represents the enthalpy change calculated for the decomposition of ammonium nitrate and label it showing the reactants, products, change in enthalpy for the reaction, AHRXn and the activation energy, Ea. Potential Energy Reactants A Reaction Progress->> Products ΔΗ Potential Energy Reactants ΔΗ B Products Reaction Progress-> 3. Use your understanding of reaction kinetics and collision theory to explain why an increase in temperature causes an increase in reaction rate. 4. Evaluate the changes in physical state that occur during the decomposition of ammonium nitrate and predict the sign on AS for the reaction. 5. Use the standard entropies, S° to determine the AS (in J K-¹ mol¹ ) for the reaction. Does the sign on AS match your prediction?

Use the following graph to answer the next question. Energy of molecules → 'B' D' E4 (E in kJ) enthalpy change B E Reaction progress → In the graph given above, what does E2 correspond to?
