I have headache from this homework. Please somebody tell how to solve.

 

PLLLEEAASE

 

 

Determine the changes of free energy, enthalpy, and entropy at 298oC for reaction 2NO2=N2O4 given the data:

 

T 273.0 291.3 322.9 346.6 372.8

Kp 65.0 13.8 1.25 0.296 0.075

Well, per the rules, nobody is going to do this for you.

 

What equations do you have at hand that may apply? What relationships do you know between free energy, enthalpy, and entropy? What assumptions do you think can be made about this problem?

 

Basically, show us what work you have done up to this point and where you are having trouble.

lol Thank you. But I solved it.

 

lnK=S/R-1/HT

 

from here was have to find slope and intercept.
