The NN bond energy is difficult to measure. Given the values of 190 kJ/mol for the NCl bond energy and 240 kJ/mol for the ClCl bond energy, determine the maximum de Broglie wavelength of an electron capable of breaking the NN bond.
Express your answer in m.

ok can some one convert 148 kj/mol inti meters?

oh dear. u probably didn't understand the question. after u got the energy for NN bond. U have to calculate lambda wavelength that too de broglie's. 0.5mv squared is the kinetic energy of the electron. So convert half mv squared to energy momentum equation. that should get u to this. P squared is equal to 2*mass of electron*Energy of the NN bond to be broken. This P valve the momentum is substituted in the lambda formula i.e., lambda = h/P i.e., planck's constant divided by the momentum u have calculated. This should give u the answer. Try it.

when you convert kj/mol to meters, you get grams..
