Q1) A constant volume tank contain 1 mole of C,H14 and 12 mole of O2 gas at a
temperature of 25 °C and 1 bar. The contents of the tank is ignited and
C,H14 is burned completely and final products temperature is found to be
1700 K. Determine the heat transfer during this process.
( take ΔΗο
= -47800 kJ/kg).
