Question
and touch it to your face. Complete the following table. Operation Stretching contraction ! AG AH TAS Practice Problems: . Suppoe yu r cunin Polymer Product and you determine that at a given temperature the reaction is spontaneous and endothermic Select the best answer from the following: a. The product possesses more entropy than the polymer. b. The heat of formation of the polymer is more positive than that of the p c. The product is more ordered in structure than the polymer. d. Since the process is endothermic, the reaction cannot be spontaneous and the data roduct. are suspect. The reaction must proceed with a decrease in entropy of the system. e.Explanation / Answer
As we know: ?G = ?H - T?S.
For a reaction to be spontaneous ?G should be negative. Since the reaction is spontaneous and endothermic, this means ?H is positive so it is not a favorable factor. So, T?S will be greater than ?H. This means entropy change ?S(Sproduct - Sreactant) is positive. So,
the correct option is (a)
