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.

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?
Answer the following True or False. For similar reactions, the reaction with the largest value of k will be faster. F F ● ● A In general, the more concentrated the reactants are, the faster the reaction goes ● A reaction which has a rate law Rate = K[A]²[B] is third order overall. • ● A catalyst makes a reaction go faster by lowering the energy of the products. A In general, the higher the temperature, the faster the reaction goes. A/
A2(g) + B2(g) →2 AB(g)
The activation energy (Ea) in the forward direction is +143 kJ. The activation energy (Ea) for the reverse direction is 75 kJ.
Draw a properly labelled potential energy diagram for the forward direction. Include ΔrH, axis, reactants and products, activation energy and activated complex. Is this reaction endothermic or exothermic?
