Answer:
A)
- Q ( kw ) for vapor = -1258.05 kw
- Q ( kw ) for liquid = -1146.3 kw
B )
- Q ( kj ) for vapor = -1258.05 kJ
- Q ( KJ ) for liquid = - 1146.3 KJ
Explanation:
Given data :
45.00 % mole of methane
55.00 % of ethane
attached below is a detailed solution
A) calculate - Q(kw)
- Q ( kw ) for vapor = -1258.05 kw
- Q ( kw ) for liquid = -1146.3 kw
B ) calculate - Q ( KJ )
- Q ( kj ) for vapor = -1258.05 kJ
- Q ( KJ ) for liquid = - 1146.3 KJ
since combustion takes place in a constant-volume batch reactor
Answer:
Only option a and b follows the first law of thermodynamics.
Explanation:
As we know that the first law of thermodynamics tells the conservation of energy,that is why it is also called quantitative law.
From the first law of thermodynamics
Q = ΔE + W
a.
Given that
W= 50 KJ,Q= 170KJ ,ΔE=120 KJ
Yes this follows the first law of thermodynamics.
b.
Given that
W= 100 Btu,Q= -110 Btu ,ΔE= -210 Btu
This also satisfy the first law of thermodynamics.
c.
Given that
W= 250 KJ,Q= -110 KJ ,ΔE=-100 KJ
Yes this does not follow the first law of thermodynamics.
d.
Given that
Yes this does not follow the first law of thermodynamics.
So only option a and b follows the first law of thermodynamics.
