Gibbs Tough Questions

IQ3: How can enthalpy and entropy be used to explain reaction spontaneity?

Students:

● explain reaction spontaneity using terminology, including:

– Gibbs free energy

– enthalpy

– entropy

● solve problems using standard references and 𝛥𝐺𝑜 = 𝛥𝐻 𝑜− 𝑇𝛥𝑆𝑜 (Gibbs free energy formula) to classify reactions as spontaneous or nonspontaneous

● predict the effect of temperature changes on spontaneity
