Assume the fuel mixture in Q4 enters the reaction chamber at 25C at 101.3kPa, with the humid air oxidiser (with 0.04molH2OforeverymolofO2) at 35C and 101.3kPa. If the products are measured as being at 800K, what is the total heat released by the reaction in kJ when 4.08kg of fuel mixture is burned completely with 20% excess air? Give only the numerical part of your answer, to 3 significant figures. QUESTION 6 Considering the reaction described in Q4, suppose we measure that 19.8kg of humid atmospheric air (with 0.04mol of H2OforeverymolofO2 ) is used in the combustion. What mass, in g, of fuel mixture can be combusted completely? Give only the numerical part of your answer, to 3 significant figures.
