8. Part A. (9 pt) For the reaction below, predict the signs for delta H system, delta S system, and delta S surrounding, AND explain your answer for each.
Homework Answers
- The sign of ΔH°sys will be negative because
one double bond will be transformed to two single bonds that is why energy will be released in this process
- The sign of ΔS°sys will be negative because
the number of reactant(s) (which is 2 ) is greater than the number of products ( which is 1) as a result entropy change will be negative.
- ( ΔS°sys + ΔS°surr) = ΔS°total > 0 because the reaction is spontaneous so ΔS°surr have to be positive in sign as ΔS°sys is negative in sign.
