Sod Posted October 9, 2006 Share Posted October 9, 2006 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 Link to comment Share on other sites More sharing options...
Bignose Posted October 9, 2006 Share Posted October 9, 2006 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. Link to comment Share on other sites More sharing options...
Sod Posted October 10, 2006 Author Share Posted October 10, 2006 lol Thank you. But I solved it. lnK=S/R-1/HT from here was have to find slope and intercept. Link to comment Share on other sites More sharing options...
