1.	The energy required to break one mole of C1-Cl bonds in12 ls 242 kJ mol-. The longest wavelength of lightcapable of breaking a single C1-Cl bond is:
Answer» Explanation: Cl2→2Cl⋅ ΔH=+242xkJ/mol I will work out the energy required to dissociate1molecule ofCl2: E=242×1036.022×1023=4.0186×10−19xJ Now I use the Planck Expression: E=hf=hcλ ∴λ=hcE λ=6.63×10−34×3×1084.0186×10−19xm λ=4.949×10−7xm λ=495xnm

The energy required to break one mole of C1-Cl bonds in12 ls 242 kJ mol-. The longest wavelength of lightcapable of breaking a single C1-Cl bond is:

Answer»

Explanation:

Cl2→2Cl⋅

ΔH=+242xkJ/mol

I will work out the energy required to dissociate1molecule ofCl2:

E=242×1036.022×1023=4.0186×10−19xJ

Now I use the Planck Expression:

E=hf=hcλ

∴λ=hcE

λ=6.63×10−34×3×1084.0186×10−19xm

λ=4.949×10−7xm

λ=495xnm
