Spontaneity

Postby Shuyi Yu 1B » Sat Feb 09, 2019 10:30 pm

If deltaH is positive and deltaS is negative, what is the spontaneity?

It would be nonspontaneous since entropy is negative and Gibbs free energy is also positive since deltaG=deltaH-TdeltaS

Using the equation given to calculate Gibbs Free Energy, you can predict the spontaneity of a system. If deltaG>0, the change is non-spontaneous. If deltaG<0, the change is spontaneous.
