Methane gas is burned with 30 percent excess air. This fuel enters a steady-flow combustor at 0.9 atm and 25'C and is mixed with the air. The products of combustion leave this reactor at 0.9 atm and 1600 K. Determine the equilibrium composition of the products of combustion and the amount of heat released by this combustion in kJ/kmol methane. Use data from the tables.

The Law of Conservation of Energy can be applied to combustion processes where fuel + oxygen products + energy The total chemical energy associated with the reactants must be the same as the total chemical energy of the products when the heat of combustion is included. a) Underline the graph which best represents the relationship between the stored chemical energy of the reactants and products in a...
A bomb calorimeter has a heat capacity of 675 J/°C and contains 925 g of water
A bomb calorimeter has a heat capacity of 675 J/°C and contains 925 g of water. If the combustion of 0.500 mole of a hydrocarbon increases the temperature of the calorimeter from 24.26°C to 53.88°C, determine the enthalpy change per mole of hydrocarbon. The specific heat of water = 4.184 J g-1 °C-1.Just the answerWhat is the enthalpy change when 175 g of C3H8 are burned in excess O2? C3H8(g) + 5 O2(g) ® 3 CO2(g) + 4 H2O(l) DH°...
