One hundred moles of CO at 300ºC is burned with 100 moles of O2 which is at 100ºC; the exit gases leave at 400ºC. What is the heat transfer to or from the system in kJ? Define whether the heat is transferred to or away from the system.

Solutions

Expert Solution

Initial 100 100 0

Final 50 0 50

Final Change in Heat = 50 * Heat of formation of CO2 - 50 * Heat of Combustion of CO

=> 50 * (-393.95) + 50 * (282.99)

=> 50 * (-393.5 + 282.99)

=> -5525 .5 KJ/mol

The heat is evolved from the system, since the reaction is exothermic in nature
