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 A.S. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction A B с observations This reaction is spontaneous only above 77. °C but proceeds at a faster rate above 159. °C. This reaction is exothermic and proceeds faster at temperatures above -3. °C. The reverse of this reaction is always spontaneous but proceeds faster at temperatures above 95. °C. conclusions AH is AS is AH is AS is AH is AS is (pick one) ✓ (pick one) positive negative unknown
