QUESTION 2 Which is true of a free energy diagram for an SN2 reaction? 0 It includes a carbocation intermediate. 0 It includes intermediates that are higher in energy than reactants or products. o It includes one transition state. o It always shows that the reaction is net exothermic. 0 The reactants are always found at a lower energy than the products.

2. Goal of this problem is to study how tunnelling in a two-well system emerges. In particular, we are interested in determining how the tunnelling rate T' of a particle with mass m scales as a function of the (effective) height Vo - E and width b of an energy barrier separating the two wells. The following graphics illustrates the set-up. Initially the particle may be trapped on the left side corresponding to the state |L〉, we are now interested...

3. (a) Show that [e-21/a (1 + 2r/a + 2r2/a?)] = -4r²e-20/a. (b) Use this result to show that the ground state wavefunction of the hydrogen atom is properly normalized: S• P(r) dr = 1. In astronomy, analysis of the photons emitted from very hot plasmas (such as are ob- served at the surface of stars, or during supernova explosions) commonly reveals spec- tral lines from...

8.4 The Two-Dimensional Central-Force Problem The 2D harmonic oscillator is a 2D central force problem (as discussed in TZD Many physical systems involve a particle that moves under the influence of a central force; that is, a force that always points exactly toward, or away from, a force center O. In classical mechanics a famous example of a central force is the force of the sun on a planet. In atomic physics the most obvious example is the hydrogen atom,...

CALCULATIONS Question 1. Write the complete expression for the free energy change of the L = V equilibrium reaction for pure water (equation 2) at 100 bars and 300-C using the following data: Gy = -210330 joules/mole GL = -210330 joules/mole Recall that the right side (water vapor) of the reaction is the product side and left side (water liquid) of the reaction is the reactant side, Recall that we always calculate...
