Question

3. During a spontaneous chemical reaction, it is found that triangle Ssys is less than 0. This means a. triangle Ssurr is less than 0 and its magnitude is less than triangle Ssys. b. triangle Ssurr is less than 0 and its magnitude is greater than triangle Ssys. c. triangle Ssurr is greater than 0 and its magnitude is less than triangle Ssys. d. triangle Ssurr is greater than 0 and its magnitude is greater than triangle Ssys. e. triangle Ssurr an error has been made, as Ssys is greater than 0 by necessity for a spontaneous process.

Explanation / Answer

S universe = S system + S surrounding

Due to 2nd law of thermodynamics: S universe > 0

Here the S system < 0

Then the S surroundings must be a big positive number!

Answer D is correct

S surrounding must be positive and greater than S syst
