Calculate the enthalpy (heat) change for reaction represented by the equation:

 is:

The given data is:

H₂ = 2H⁺ + 2e^–, E° = 0.00 V

Ag⁺ + I^– = Agl + e^–, E° = –0.15 V

Calculate the E.M.F. of the cell:

H₂/Hl/ soln. || Agl/Ag is:

For a bimolecular reaction,

A + BC  C

The activation energy is E₀ in the gas phase. If the reaction is carried out in a confined volume of λ³, determine the activation energy.

Calculate the Raman shift if a sample was excited by the 4358Å line of mercury. A Raman line was observed at 447Å.
