12.1—That, since endothermic reactions can occur spontaneously at room temperature, enthalpy changes alone do not control whether

Understand that, since endothermic reactions can occur spontaneously at room temperature, enthalpy changes alone do not control whether reactions occur.

Use —that, since endothermic reactions can occur spontaneously at room temperature, enthalpy changes alone do not control whether to connect the rule to the data and decision in the question.

This matters because —that, since endothermic reactions can occur spontaneously at room temperature, enthalpy changes alone do not control whether determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —that, since endothermic reactions can occur spontaneously at room temperature, enthalpy changes alone do not control whether to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —That, since endothermic reactions can occur spontaneously at room temperature, enthalpy changes alone do not control whether is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
