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?
