Answer:
-45.37 kJ
Explanation:
The work done for the explosion of 2 moles of TNT can be determined by taking the product of the pressure and change in volume. In addition, the explosion of a substance is endothermic in nature. Thus, we have the equation for work done as:
W = P*dV
Where:
W = work done (L*atm)
P = pressure (atm) = 1.0 atm
dV = change in volume (L) = 0.274 - 448 = -447.726 L
Therefore,
W = 1.0 * (-447.726) = -447.726 L*atm
1 L*atm is equivalent to 101.325 J
Thus, the work done in kJ is:
-447.726*101.325/1000 = -45.37 kJ
