Liquid ethanol (C,H;OH) at 25°C, 1 atm enters an insulated reactor operating at steady state and burns completely with air entering at 370 K, 1 atm. The combustion products exit at 1300 K. Kinetic and potential energy effects can be neglected and the air can be modeled as 21% O, and 79% N, on a molar basis. Determine the percent excess air used.

Question
X Your answer is incorrect. Liquid ethanol (CH;OH) at 25°C, 1 atm enters an insulated reactor operating at steady state and burns completely with air entering at 370 K, 1 atm. The combustion products exit at 1300 K. Kinetic and potential energy effects can be neglected and the air can be modeled as 21% O, and 79% N2 on a molar basis. Determine the percent excess air used. 51
