PopularLimestone 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. correct answersB. 
positive and greater than TΔS., the reaction does not occur, ΔG = ΔH - TΔS > 0. From inspection of the reaction, it can be concluded that ΔS > 0 (a gas evolves). Consequently, ΔH > TΔS explains why the reaction does not occur
