(a)
Interpretation:
Whether the reaction is exothermic or endothermic when ΔH; change of enthalpy is negative needs to be explained.
Concept Introduction:
Enthalpy change can be defined as energy difference for breaking of bond in
(b)
Interpretation:
Whether the reaction is exothermic or endothermic when the energy of reactants is lower than the energy of products needs to be determined.
Concept Introduction:
In an endothermic reaction, energy is required whereas in exothermic reactions, energy is released.
(c)
Interpretation:
Whether the reaction is exothermic or endothermic when the energy is absorbed in the reaction needs to be determined.
Concept Introduction:
In an endothermic reaction, energy is required whereas in exothermic reactions, energy is released.
(d)
Interpretation:
Whether the reaction is exothermic or endothermic if the bonds in products are stronger than the bonds in reactants needs to be explained.
Concept Introduction:
Enthalpy change can be defined as energy difference for breaking of bond in chemical reactions and the formation of new bonds. This describes for a system at constant pressure. In an endothermic reaction, energy is required whereas in exothermic reactions, energy is released.

- 4.60 Why are fuel additives used?arrow_forwardEnthalpy a A 100.-g sample of water is placed in an insulated container and allowed to come to room temperature at 21C. To heat the water sample to 41C, how much heat must you add to it? b Consider the hypothetical reaction,2X(aq)+Y(l)X2Y(aq)being run in an insulated container that contains 100. g of solution. If the temperature of the solution changes from 21C to 31C, how much heat does the chemical reaction produce? How does this answer compare with that in part a? (You can assume that this solution is so dilute that it has the same heat capacity as pure water.) c If you wanted the temperature of 100. g of this solution to increase from 21C to 51C, how much heat would you have to add to it? (Try to answer this question without using a formula.) d If you had added 0.02 mol of X and 0.01 mol of Y to form the solution in part b, how many moles of X and Y would you need to bring about the temperature change described in part c. e Judging on the basis of your answers so far, what is the enthalpy of the reaction 2X(aq) + Y(l) X2Y(aq)?arrow_forwardConsider the two space shuttle fuel reactions in Exercises 81 and 82. Which reaction produces more energy per kilogram of reactant mixture (stoichiometric amounts)? 81. The reusable booster rockets of the space shuttle use a mixture of aluminum and ammonium perchlorate as fuel. A possible reaction is 3Al(s)+3NH4ClO4(s)Al2O3(s)+AlCl3(s)+3NO(g)+6H2O(g) Calculate H for this reaction 82. The space shuttle Orbiter utilizes the oxidation of methylhydrazine by dinitrogen tetroxide for propulsion: 4N2H3CH3(l)+5N2O4(l)12H2O(g)+9N2(g)+4CO2(g) Calculate H for this reactionarrow_forward
