12.10—Reactions can occur as long as ∆Stotal is positive even if one of the other entropy changes is negative

Understand that reactions can occur as long as ∆Stotal is positive even if one of the other entropy changes is negative.

Use —reactions can occur as long as ∆stotal is positive even if one of the other entropy changes is negative to connect the rule to the data and decision in the question.

This matters because —reactions can occur as long as ∆stotal is positive even if one of the other entropy changes is negative determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —reactions can occur as long as ∆stotal is positive even if one of the other entropy changes is negative to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Reactions can occur as long as ∆Stotal is positive even if one of the other entropy changes is negative is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
