The reaction between H_(2) and Br_(2) to form HBr in presence of light is initiated by the photo decomposition of Br_(2) into free Br atoms (free radicals) by absorption of light. The bond dissociation energy of Br_(2) is 192kJ//"mole" .What is the longest wavelength of the photon that would initiate the reaction?

The bond dissociation energy depends upon the nature of the bond and nature of the molecule. If any molecule more than 1 bonds of similar nature are present then the bond energy reported is the average bond energy. Determine C-C and C-H bond enthalpy (in kJ/mol). Given: Delta_(f)H^(0) (C_(2)H_(6),g)= -85kJ//mol, Delta_(f) H^(0) (C_(3)H_(8), g)= -104kJ//mole, Delta_("sub")H^(0) (C,s)= 718kJ//mol , B.E. (H-H)= 436 kJ/mol,

If the energy absorbed by each X_2 molecule of a gas is 3.5xx10^-19 J and the bond energy of X_2 is 180.6 kJ mol^-1 then the kinetic energy per atom will be

Ozone in the upper atmoshphere absorbs ultraviolet radiation which induces the following chemical reaction O_(3)(g)rightarrowO_(2)(g)+O(g) O_(2) produced in the above photochemical dissociation undergoes further dissociation into one normal oxygen atom (O) and more energetic oxygen atom O** . O_(2)(g) rightarrowO+O** (O**) has 1 eV more energy than(O) and normal dissociation energy of O_(2) is 480 kJ "mol"^(-1) . [1 eV/Photon =96 kJ "mol"^(-1) ] What is the maximum wavelength effective for the photochemical dissociation of O_(2) molecule

N_(2) undergoes photochemical dissociation into one normal N- atom and one N- atom having 0.1eV more energy than normal N- atom. The dissociation of N_(2) into two normal atom of N requires 289.5 KJ//mol energy. The maximum wavelength effective for photochemical dissociation of N_(2) in nm is P nm ( 1 eV = 96.5 KJ/mol). Find the value of (P)/(100) .
