Calculate the wavelength of light required to break the bond between two bromine atoms in a bromine molecule?

The Br— Br bond energy is 193 kJ mol– 1.


Bond best answer:

Answer by m_skokin
Convert the bond energy to eV:

1Kj/mol = .01036427eV/mol

So that gives you 2eV/mol of Br-Br.

Apply eq. lambda = h*c/E

where h = 4.136*10^ -16 eV*s and c = 2.998 * 10^ 8 m/s

and you get lambda (or frequency) = 6.2 * 10 ^ -8 m

Paseo/Bond Bridges - July 7, 2010

The old making way for the new.

The Paseo bridge is being replaced with the Bond bridge.

The Paseo bridge has been around for about 50 years or so. The Bond bridge is scheduled for a 2011 opening.

These bridges carry north and southbound federal highways I-29 and I-35 across the Missouri river at Kansas City, Missouri.
