(a) Draw the transition state for the reverse reaction of Eq. 4.30. Compare it with the transition state shown in Eq. 4.31. (b) What general statement can you make about the transition-state structures for a reaction and its reverse?
• Isothermal Process o ∆S = q rev o q rev flow of heat for reversible process • Gibbs Free Energy (G)- maximum energy released that is available to do work o constant temperature and pressure o ∆G = ∆H -T∆S o ∆H = ∆G +T∆S o efficiency = work done divided by energy produced Chapter 13: Chemical Kinetics • Kinetics- rate of the change of concentrations of substances in chemical reactions o Reaction Rate- how quickly reaction occurs; concentration change over time o Reactant molecules must collide with sufficient energy (above activation energy) to form products o Factors effecting rate- physical state, concentration, temperature, and catalyst
