Carbon monoxide (CO) is burnt in presence of 200% excess pure oxygen and the flame temperature achieved is 2298 K. The inlet streams are at 25°C. The standard heat of formation (at 25°C) of CO and CO2 are -110 kJ mol-1 and -390 kJ mol-1, respectively. The heat capacities (in J mol-1K-1) of the components are
CPO2=25+14×10-3T
CpCO2=25+42×10-3T
where, T is the temperature in K. The heat loss (in kJ) per mole of CO burnt is
CPO2=25+14×10-3T
CpCO2=25+42×10-3T
where, T is the temperature in K. The heat loss (in kJ) per mole of CO burnt is
Correct : 35.0
