Textbook Problem 5.59

Postby Joey_Okumura_1E » Wed Feb 17, 2021 7:48 pm

For part g, I calculated the enthalpy change to determine the answer. Is there a different method I should have used to figure out the answer? (Maybe one that includes using Gibbs free energy instead?)

Nope, that seems like the correct thing to do. Temperature can be thought of as adding or removing heat, so you would want to know whether your reaction is endothermic or exothermic, hence finding dH for the reaction

Since we're assuming the delta H is the same across all temperatures, would we just plug in an arbitrary higher T2 value into the Van't Hoff equation and then find the new K value?

Sorry, nevermind. I realize that K was not the quantity specified for part g. Please disregard my last post.
