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
