The reaction which has negative sign of standard entropy change out of the given reactions is to be determined. Concept Interpretation: The entropy of the system depends upon the randomness. As the randomness of the system increases, the entropy of the system increases. To determine: The sign of entropy change of system in the given reaction.

If so, draw a synthesis below. If no synthesis using reagents ALEKS recognizes is possible, check the box under the drawing area.
Be sure you follow the standard ALEKS rules for submitting syntheses.
