0 Ermor 404 jNot Foundiit My Answers Give Up Correct Part B An ideal gaseous reaction (which is a hypothetical gaseous reaction that conforms to the laws governing gas behavior) occurs at a constant pressure of 300 atm and releases 58 2 kJ of heat Before the reactonthhe volurme ofthe system was 780 L Calculate the total menal energy charge, E. in kipules Express your answer with the appropriate units. After reaction the vohme ofre system was 260 L Hints AE-Value k My Answes Give Up Incorrect; Try Again;3 attempts remaining State functions versus path functions g and e are path functions because they depend on the path of change and not just the nital and al stahes of the se Part C in separate with re e .Explanation / Answer
B)
P = 30 atm = 30*101.325= 3039.75 kPa
Q = -58.2 kJ ( release)
V1 = 7.8 L
V2 = 2.6 L
dE = Q- W
dE = -58.2 - W
W = -P*dV = -P(Vf-vi) = -3039.75 * (2.6 -7.8 )*10^-3 = 15.8067 kPa
dE = -58.2 - 15.8067
dE = -74.0067 kJ
