Question
In the lab, two mystery compounds are mixed together in a beaker. The solution immediately changed color and the temperature of the solution quickly increased. Which of the following correctly explains the entropy changes of the system?
Question options:
The entropy of the system increased more than the entropy of the surroundings decreased.
The entropy of the system decreased by the same amount that the entropy of the surroundings increased.
The reaction was endothermic.
The entropy of the universe decreased.
The entropy of the system increased more than the entropy of the surroundings decreased.
The entropy of the system decreased by the same amount that the entropy of the surroundings increased.
The reaction was endothermic.
The entropy of the universe decreased.
Explanation / Answer
The reaction is exothermic because heat is evolved in reaction.
Entropy of the universe never decreased .
Entropy of system increases if temperature increases,but in same amount entropy of surrounding decreases.
Option 1 and 3
