(a) Let's reconsider particle-in-a-box model (with 12 electrons) in question 1 by modifying a
rectangular particle-in-a-box. When the height of box in Q1 is reduced to a half (see below),
construct an energy-level diagram showing the relative energy ordering of the lowest 8
molecular orbitals when this cube is a xa x 0.5a. Label the levels in terms of their quantum
numbers and Eo (Eo = h2/8ma²). Be alert for degeneracies.

Calculate the uncertainty in the momentun of an electron laying in a state with uncertainty in its position of 5×10^10m
. Suppose a quanton's wavefunction at a given time is y(x) = A[1 + (x/a)2]-¹, where A is an
unspecified constant and a = 4.0 nm. According to the table integrals
dx

[1 + (x/a)²]² = 1 + (x/a)²+2tan ¹ (2)
If we were to perform an experiment to locate the quanton at this time, what would the
probability of a result between x = 0 and x = 8.0 nm?
