17.27—A heterogeneous catalyst is in a different phase from the reactants and that the reaction occurs at the surface of

Know that a heterogeneous catalyst is in a different phase from the reactants and that the reaction occurs at the surface of the catalyst.

Use —a heterogeneous catalyst is in a different phase from the reactants and that the reaction occurs at the surface of to connect the rule to the data and decision in the question.

This matters because —a heterogeneous catalyst is in a different phase from the reactants and that the reaction occurs at the surface of determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —a heterogeneous catalyst is in a different phase from the reactants and that the reaction occurs at the surface of to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —A heterogeneous catalyst is in a different phase from the reactants and that the reaction occurs at the surface of is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
