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 A B с observations The reverse of this reaction is always spontaneous. This reaction is always spontaneous, but proceeds slower at temperatures above 27. °C. This reaction is exothermic and proceeds slower at temperatures below 61. °C.
