Calorific value and ignition temperature of fuel X are 75 kj/g and 20� – InterviewSolution

1.	Calorific value and ignition temperature of fuel X are 75 kj/g and 20∘C respectively. These values for fuel Y are 50 kj/g and 75∘C respectively. On burning, the fuel Y produces only CO2 while fuel X produces CO2 and CO. Which of the two is a better fuel? Give two reasons to support your answer.
Answer» Calorific value and ignition temperature of fuel X are 75 kj/g and $20^{\circ} C$ respectively. These values for fuel Y are 50 kj/g and $75^{\circ} C$ respectively. On burning, the fuel Y produces only $C O_{2}$ while fuel X produces $C O_{2}$ and CO. Which of the two is a better fuel? Give two reasons to support your answer.
