Explain the combustion reaction produces heat energy

Reference no: EM13522194

A sample of coal is completely burned in a 10.0 L cylinder at a constant pressure of 1.10 atm and a temperature of 1000 oC. The combustion reaction produces 2.3x104 J of heat energy. As the gaseous products expand they push against a piston which increases the cylinder volume to 55.0 L. After combustion the gases are allowed to reach equilibrium. A chemical analysis shows that there are 15.7 moles of O2 and 9.8 moles of CO2 in the cylinder at equilibrium. A second combustion experiment is carried out at a temperature of 1455 oC. Using the information above calculate the equilibrium constant you would expect to measure for the experiment carried out at the higher temperature.
