Question

a bulb takes 10 seconds to dissociate all the molecules in 10^-4 moles of chlorine bond energy of cl-cl bond is 3.2*10^-17 joule/ molecule power of the bulb in watt is​

Answer 1

Answer:

For calculation of longest wavelength of light that can break Cl-Cl bond can be found by using Formula E = Nhc/λ

where h= planck's constant, c = speed of light, λ = wavelength of light, n = no of molecules (no. of photon required) and N

A

= Avogadro's Number

λ =
