Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions A The reverse of this reaction is always spontaneous but proceeds slower at temperatures below -5. °C. ΔΗ is (pick one) ✓ AS is (pick one) ΔΗ is B This reaction is endothermic and proceeds faster at temperatures above 134. °C. (pick one) AS is (pick one) This reaction is spontaneous only above AH is (pick one) C 132. °C but proceeds at a faster rate above 161. °C. AS is (pick one) ✓
