Not sure but is it D?
I don't have answer, what did you do?
∆U=ZTM/m (enthalpy at constant volume)
Z= thermal capacity T= rise in temp
m= weight of substance M=molar mass
I am getting -3200 .67 and -3201.9 only check calculation
-∆H*0.1=∆T(S + nCp)
But I'm not sure if we should consider the nCp or not.
for (ii) what did you take delta ng as?
Anyway delta Cp is given 0.
I did the same as you but I am getting 3333.33
∆Cp is zero which implies ∆Hf won't change with temperature
But how did you get did
I got D by 10010000.1/(3+0.7) still let's wait for someone else to attempt.
A few basic doubts. In physics. What do they exactly mean when they say these terms.
Slow or fast indicates if it's a quasi static process or not
Insulating means no heat exchange thru it
And what do they mean when they say a system remains in internal equilibrium. Does that mean that force on piston on both sides at all times is equal?
