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 C observations This reaction is slower below 18. °C than above. This reaction is spontaneous only above 97. °C. This reaction is always spontaneous, but proceeds faster at temperatures above 72. °C.
