Question

During a spontaneous chemical reaction, it is found that delta S sys is less than 0. This means______ a. delta S surr is less than 0 and its magnitude is less than delta S sys. b. delta S surr is less than 0 and its magnitude is greater than delta S sys. c. delta S surr is greater than 0 and its magnitude is less than delta S sys. D. delta S surr is greater than 0 and its magnitude is greater than delta S sys e. an error has been made, as S sys is greater than 0 by necessity for a spontaneous process.

Explanation / Answer

S universe > 0 by the second law of thermodynamics

S universe = S syste + S surr

If S sys < 0

then S surr must be greater than 0 and greater in magnitude (so the addition is greater than 0 and satisfies the 2nd law

Correct answer is D
