Sagot :
Answer:
W = -10.3 kJ
Explanation:
During combustion, the system performs work and releases heat. Therefore, the change in internal energy is negative, and the change in enthalpy, which is equal to heat at constant pressure, is also negative. Work is then calculated by rearranging the equation for the change in internal energy:
w=ΔE−qp=−5084.3 kJ−(−5074.0 kJ)
The release of heat is much greater than the work performed by the system on its surroundings. The potential energy stored in the bonds of octane explains why considerably large amounts of energy can be lost by the system during combustion.
The work done during the combustion is mathematically given as
w= −10.3kJ
What is the work done during the combustion?
Question Parameter(s):
The change in internal energy for the combustion of 1.0 molmol of
octane at a pressure of 1.0 atmatm is -5084.1 kJkJ .
Generally, the equation for the workdone is mathematically given as
w=ΔE−qp
w=−5084.3 kJ−(−5074.0 kJ)
w= −10.3kJ
In conclusion, the work done
w= −10.3kJ
