🤓 Based on our data, we think this question is relevant for Professor Randles' class at UCF.
Predict the sign of the entropy change, ΔS°, for each of the reaction displayed. Drag the appropriate items to their respective bins.
We’re being asked to predict the sign of the entropy change (ΔS) for the given reactions. Recall that if:
• ΔS > 0 or ΔS = (+); entropy is increased
• ΔS < 0 or ΔS = (–); entropy is decreased
Remember that phase changes lead to a change in entropy:
Also, recall that an increase in the number of gas molecules in the reaction also leads to an increase in entropy.
