an energy value of 3.313x10^-19 joules is needed to break a chemical bond. what is the wavelength of energy needed to break the bond? (the speed of light = 3.00x10^10 cm/sec; planck's constant = 6.636x10^-34 J . sec
is there a formula i'm missing?
Formula (memorize this)
Energy = frequency * plancks constant.
find the frequency, then (memorize this)
frequency*wavelength= speedlight
The formula you need is the Einstein photoelectric effect equation;
h c/(wavelength) = Energy required
In this case, the equation is applied to radiative chemical dissociation, or "photolysis".
They have given you c (the light speed) and h (Planck's constant). Solve for the wavelength
thanks so much, that one really confused me.
