(a)
Interpretation:
The transition states in graph needs to be identified as endothermic or exothermic reactions.
Concept introduction:
Exothermic reaction releases heat as energy to the environment while endothermic reaction absorbs heat from the surrounding environment. This phenomenon makes significant differences in the energy diagram of these 2 reactions.
(b)
Interpretation:
By considering the amount of activation energy of the 2 reactions, the faster reaction can be selected.
Concept introduction:
Activation energy of a reaction is the amount of energy that must be provided to start a
(c)
Interpretation:
The products in an energy diagram and the reaction coordinate needs to be determined.
Concept introduction:
Products of a chemical reaction is represented by the final point of the reaction coordinate axis of an energy diagram.
(d)
Interpretation:
The transition states in the energy diagram needs to be identified.
Concept introduction:
Transition state is the state relevant to the highest energy through the reaction coordinate.
(f)
Interpretation:
The change in enthalpy for the reaction needs to be labeled.
Concept introduction:
Enthalpy of a reaction is the energy change occurs in the system, during the particular reaction. Enthalpy of a reaction is measured as kilo Joules per mole (kJ mol-1) or kilo calories per mole (kcal mol-1).

- xplain why aluminum cans make good storage containers for soft drinks. Styrofoam cups can be used to keep coffee hot and cola cold. How can this be?arrow_forward. A(n) _______ speeds up a reaction without being consumed.arrow_forwardInsoluble AgCl(s) precipitates when solutions of AgNO3(aq) and NaCl(aq) are mixed. AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq) rH = ? To measure the energy evolved in this reaction, 250. mL of 0.16 M AgNO3(aq) and 125 mL of 0.32 M NaCl(aq) are mixed in a coffee-cup calorimeter. The temperature of the mixture rises from 21.15 C to 22.90 C. Calculate the enthalpy change for the precipitation of AgCl(s), in kJ/mol. (Assume the density of the solution is 1.0 g/mL and its specific heat capacity is 4.2 J/g K.)arrow_forward
