11.3—Select and justify a suitable experimental technique to obtain rate data for a given reaction

Be able to select and justify a suitable experimental technique to obtain rate data for a given reaction, including: i titration ii colorimetry iii mass change iv volume of gas evolved v other suitable technique(s) for a given reaction.

Use —select and justify a suitable experimental technique to obtain rate data for a given reaction to connect the rule to the data and decision in the question.

This matters because —select and justify a suitable experimental technique to obtain rate data for a given reaction determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —select and justify a suitable experimental technique to obtain rate data for a given reaction to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Select and justify a suitable experimental technique to obtain rate data for a given reaction is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
