Answer question (BOX ANSWER)

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 AH is pick one v A This reaction is spontaneous only below 80. C. AS is (pick one) AH is (pick one) B This reaction is always spontaneous, but proceeds faster at temperatures above -17. C. AS is (pick one) AH is (pick one) The reverse of this reaction is always spontaneous but proceeds faster at temperatures above 53. C. AS is (pick one)
