Answer:
1.949 × 10 ⁻⁷ m
Explanation:
Constant needed
Planck constant (h) = 6.626 × 10⁻³⁴mkg/s²
speed of light (c)= 3.0 × 10⁸ m/s
Avogadro number =6.02 × 10²³
Energy per molecule (E) = energy needed to break the bond / Avogadro constant
E = (6.14 × 10⁵ Jmol) / ( 6.02 × 10²³) = 1.0199 × 10⁻¹⁸ J per molecule
E of photon = hv where v is minimum frequency
c = vλ
c /λ = v
E = h c /λ
λ = hc / E = ( 6.626 × 10⁻³⁴ mkg/m² × 3.0 ×10⁸ m/s) / (1.0199 × 10⁻¹⁸ J) = 1.949 × 10 ⁻⁷ m
