Chemistry - fitting ExampleQuestion 1En=-(13.6eV*z)/n, because z=4it can be written as En=-16*13.6eV / nii) the dependence of quatum numbers n upon l is given by the following formulal=n-12(2*l+1)=2* niii) n=2 for glucinium, so l=1 and can not be 3d) iii) energy emitted by photon Einf- E2= 0+54.4eV=54.4 eV= 54.4*1.6*10-19 J=8,7*10-18 J8,7*10-18 Jnow we should express photons frequency from it energyE=h*f = f=E/hf= 8,7*10-18 J/6.63*10-34 J*s=1.31*1016 1/s1.31*1016 Hz is ultraviolet spectrumiv) the energy of the lowest energy photon which can be absorbed by beryllium ion isE2-E1=-54.4eV+217.6=163.2 eVv) it could absorb a photon of a lower energy if its electron was on a higher(prenominal) energetic leveli) E1=-16*13.6eV / 1=-217.6eV E2=-16*13.6eV / 4= -54.4eV E3=-16*13.6eV / 9 = -3.067eV Eoo=-16*13.6eV/inf = 0Question 3- because H0 (=29kJ) response is endothermic- I2+Cl2 =2ICL (-29kJ)H=2HICL-HCl2-HI2- equilibrium will not change as the number of molecules in the remaining part of th e equation equals to the number of molecules in the right part of the equation I2+Cl2 =2ICL 1+ 1=2 - because its endothermic reaction the increase of temperature will cause the shift of equilibrium to the right (forming of ICl)- the reaction will pass faster with the following rate lg (k(T2/T1)) where k is the reaction rate coefficient- the presence of particle accelerator will cause the reaction rate to increase, the equilibrium will cause the shift to the right (forming of ICl) as catalyst mainly reduces activation energy.
