Question

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
