Clarification on what temperature reaction will be spontaneous

Postby Samantha Chung 4I » Tue Feb 26, 2019 9:39 pm

Just to clarify, but if a question asks: at what temperature X reaction will be spontaneous, and the answer based on inequalities is anything below temperature Y for instance, do I write that, or can I just write any number?

You should solve for Temperature "Z" where deltaG=0 and explain that the reaction is at equilibrium at this point. Then to answer the question, you should write it as an inequality (ie: when Temperature> tempZ, the reaction is spontaneous in the forward direction). If you want to be extra, you can give an example of a temperature where the reaction is spontaneous, but I'm pretty sure you don't need to.
