Imagine you are working in a lab, and you are performing two chemical reactions. Y notice that Reaction A occurs much faster than Reaction B, and that both reactions release the same amount of heat. Which of the following conclusions can be made from your observation? Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is more negative (i.e., a larger negative number) than the AG for Reaction B. Reaction A has a lower activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has a higher activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is less negative (i.e., a smaller negative number) than the AG for Reaction B.

uce 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 Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions The reverse of this reaction is always spontaneous but proceeds slower at temperatures below 132. °C. AH is (pick one) AS is (pick one) His (pick one) B This reaction is endothermic. AS is (pick one) This reaction is spontaneous except below 110. °C but proceeds at a slower rate below 135. °C. AH IS (pick one) AS is (pick one)v

Fill in blank:   An ES complex that releases 30 kj/mol of binding free energy will _____ (raise or lower) the activation energy barrier needed to reach the transition state.
