Students investigate which metal is best to use as storage material in hydrogen cars. In this chemistry lesson, students differentiate endothermic and exothermic reactions. They write a reflection paragraph about what they learned in the...

In this spontaneous reactions activity, students read about entropy, enthalpy and Gibbs free energy. They complete a table with reaction conditions and determine if the reaction is spontaneous or not. They solve three problems about free...

In this chemistry instructional activity, students solve 2 problems on Gibbs free energy. They calculate the standard free energy of formation for given reactions.
