Hydrogen (H2) reacts with 400% theoretical air in an isothermal reaction where the initial and final conditions are 25 and 1 atm pressure. The surroundings temperature is also at 25. Answer the following questions. i) How much heat is transferred from the combustor during this process (per kmol of hydrogen)? ii) How much entropy is generated per unit mass of the burned fuel? iii) What is the reversible work (per unit mass of the burned fuel) that could have been produced in this process? iv) Is there any other way to utilise the energy of this hydrogen and air mixture? If so, does that way destroy more or less exergy? Briefly explain why.

Q2) Hydrogen (H2) reacts with 400% theoretical air in an isothermal reaction where the initial and final conditions are 25C and 1 atm pressure (see Figure Q2 ). The surroundings temperature is also at 25C. Answer the following questions. i) How much heat is transferred from the combustor during this process (per kmol of hydrogen)? ii) How much entropy is generated per unit mass of the burned fuel? iii) What is the reversible work (per unit mass of the burned fuel) that could have been produced in this process? iv) Is there any other way to utilise the energy of this hydrogen and air mixture? If so, does that way destroy more or less exergy? Briefly explain why. [7]
