- The Ostwald process for the commercial production of nitric acid from ammonia and oxygen involves the following steps: 4NH3(g)+5O24NO(g)+6H2O(g)2NO(g)+O2(g)2NO2(g)3NO2(g)+H2O(l)2HNO3(aq)+NO(g) a. Use the values of Hf in Appendix 4 to calculate the value of H for each of the preceding reactions. b. Write the overall equation for the production of nitric acid by the Ostwald process by combining the preceding equations. (Water is also a product.) Is the overall reaction exothermic or endothermic?arrow_forward9.84 Some claim it would be more logical to use heats of atomization, the energy required to convert any molecule to its separated atoms, rather than heats of formation for doing calculations with Hess's law. If you had a table of heats of atomization and calculated the combustion energy of a fuel, would you get the same answer as you would get using heats of formation? Explain your answer.arrow_forward(a) Calculate the enthalpy change, rH, for the formation of 1.00 mol of strontium carbonate (the material that gives the red color in fireworks) from its elements. Sr(s) + C(s) + 32, O2(g) SrCO3(s) The experimental information available is Sr(s) + O2(g) SrO(s) fH = 592 kJ/mol-rxn SrO(s) + CO2(g) SrCO3(s) rH = 234 kJ/mol-rxn C(graphite) + O2(g) CO2(g) fH = 394 kJ/mol-rxn (b) Draw an energy level diagram relating the energy quantities in this problem.arrow_forward
- The first step in the preparation of lead from its ore (galena, PbS) consists of roasting the ore. PbS(s)+32O2(g)SO2(g)+PbO(s) Calculate the standard enthalpy change for this reaction, using enthalpies of formation (see Appendix C).arrow_forwardIf takes 1.25 kJ of energy to heat a certain sample of pure silver from 12.0 °C to 15.2 °C. Calculate the mass of the sample of silver.arrow_forwardHigh-quality audio amplifiers generate large amounts of heat. To dissipate the heat and prevent damage to the electronic components, heat-radiating metal fins are used. Would it be better to make these fins out of iron or aluminum? Why?
