Question
Reactants typically adsorb onto the surface of this type of catalyst. For 10 points each:
[10m] Name these catalysts that, during a reaction, exist in a different phase to the reactants.
ANSWER: heterogeneous catalysts
[10h] This principle states that there is an optimal strength of interaction between a substrate and a heterogeneous catalyst, above or below which the reaction rate declines.
ANSWER: Sabatier (sah-bah-TYAY) principle
[10e] The Sabatier principle is often illustrated using "plots" named for these landforms. A classic chemistry demonstration uses a mixture of baking soda and vinegar to imitate one of these landforms.
ANSWER: volcanoes [or volcano plots]
