2. [15 Pts] In a gas stove, stoichiometric combustion from 1 mole of an unknown saturated hydrocarbon chain is producing 6 moles of \( \mathrm{CO}_{2} \). The reactants enter the combustion chamber at the standard reference conditions \( \left(25^{\circ} \mathrm{C}, 100 \mathrm{kPa}\right) \). There is no work done in this combustion, and the heating efficiency is \( 80 \% \). Combustion product pressure is 120 kPa . Use (A.5) instead of (A.9). (a) What is the product temperature? [6 Pts] (b) What is the fuel chemical efficiency (mass basis)? [6 Pts] (c) What is the fuel consumption rate in \( \mathrm{kg} / \mathrm{s} \), if the heat provided from the stove is 1 MW ? [3 Pts]
