Question

A light photon with a frequency of at least 0.0906 x 10^16 Hz is required to split apart hydrogen bromide according to the equation:

HBr(g) --> H(g) + Br(g)
Calculate the energy (kJ) required to break apart a mole of hydrogen bromide. Express answer in scientific notation.

Answer 1

Hmm idk the answer

Answer 2

Energy of 1 photon = h*frequency
Energy of 1 mol of photons is that x 6.02E23 in J. Divide by 1000 to convert to kJ.

Answer 3

thank you very much that was great help..
