Sec. # (last four digits)___________ Data/Information: R = 8.31 joules/mole-K = 1.987 cal/mol-K Speed of light = 3.00 x 108m/s Avagadro's Number = N = 6.022 x 1023mole–1Faraday constant F= 96,500 coulombs/mol Planck’s constant = h =6.63 x 10–34Joule-sec 1 Joule = 1 kg m2/s21 volt = 1 joule/coulombEn=k[Z2/n2]k= 2.18 10–18Joules {Enis the energy for the nthenergy level} E= E° – 0.059/n log10Q (at room temp)E= E° – RT/nFlog10Q T(K) = T(C) + 273 k = Ae–Ea/RTPeriodic Table attached. Reduction Potentials provided as needed 1.(10)Use M.O. theory (show your work or reasoning) to answer the following questions. (a) Which of the following species would you expect to have the shortest bond length, CO+CO, or CO? ,
(b) Predict which of the following has the largest bond energy, i.e., requires the most energy to break apart the C and N atoms, CN+, CN, or CN.
Thinking in terms of crystal field theory, orbital electron occupation and favorable vs unfavorable reactivity (i.e., thermodynamics), briefly explain why the reduction potential for Fe3+lies below those for the +3 oxidations of the elements on both sides of it in the periodic table (manganese and cobalt).
