5. A mixture consisting of 100. moles of hydrogen gas and 2500. moles of air (80.0 mol % nitrogen gas and 20.0 mol % oxygen gas), initially at 25°C, reacts to produce water vapor (and no nitrogen oxides). The pressure is constant at I atm, and the system is adiabatic (no heat exchange between the system and surroundings). The molar heat capacities are: 5.9 cal/mol°C for water vapor; 6.9 cal/mol°C for N2 and O2. Calculate the maximum temperature achieved by this system.

In the 1880s, Frederick Trouton noted that the enthalpy of vaporization of 1 mol pure liquid is approximately 88 times the boiling point, Tb, of the liquid on the Kelvin scale. This relationship is called Troutons rule and is represented by the thermochemical equation liquid gas H = 88 Tb, joules Combined with an empirical formula from chemical analysis, Troutons rule can be used to find the molecular formula of a compound, as illustrated here. A compound that contains only carbon and hydrogen is 85.6% C and 14.4% H. Its enthalpy of vaporization is 389 J/g, and it boils at a temperature of 322 K. (a) What is the empirical formula of this compound? (b) Use Troutons rule to calculate the approximate enthalpy or vaporization or one mole of the compound. Combine the enthalpy of vaporization per mole with that same quantity per gram to obtain an approximate molar mass of the compound. (c) Use the results of parts (a) and (b) to find the molecular formula of this compound. Remember that the molecular mass must be exactly a whole-number multiple of the empirical formula mass, so considerable rounding may be needed.
Would the amount of heat absorbed by the dissolution in Example 5.6 appear greater, lesser, or remain the same if the heat capacity of the calorimeter were taken into account? Explain your answer.
Nitromethane, CH3NO2, is a good fuel. It is a liquid at ordinary temperatures. When the liquid is burned, the reaction involved is chiefly 2CH3NO2(l)+32O2(g)2CO2(g)+N2(g)+3H2O(g) The standard enthalpy of formation of liquid nitromethaneat 25°C is 112kJmol1; other relevant values can be found in Appendix D. Calculate the enthalpy change in the burning of 1 molliquid nitromethane to form gaseous products at25°C. State explicitly whether the reaction is endothermicor exothermic. Would more or less heat be evolved if gaseous nitromethanewere burned under the same conditions?Indicate what additional information (if any) you would need to calculate the exact amount of heat, and show just how you would use this information.
