AAMC MCAT Exam 4- Chem/Phys| QUESTIONS &ANSWERS| ALREADY PASSED|VERIFIED & UPDATED Limestone does NOT decompose when heated to 900 K because, at 900 K, ΔH is: A. positive and less than TΔS. B. positive and greater than TΔS. C. negative and less than TΔS. D. negative and greater than TΔS. - ANSWER B. positive and greater than TΔS. The reaction does not occur (is not spontaneous). This indicates that ΔG = ΔH - TΔS > 0. From inspection of the reaction, it can be concluded t...
