The quantum yield of light-induced chemical reactions (calledphotochemical reactions) measures the efficiency of theprocess. The quantum yield,d, is defined4,as:number of reaction eventsnumber of photons absorbed Suppose the quantum yieldfor the reaction CH;X - CH3 + X is =0.24. A cuvette con-taining a solution of CH3X is irradiated with 280-nm light witha power of 885 mW for 10.0 minutes. Assuming total absorp-tion of the light by the sample, what is the maximum amount(in moles) of CH3X that breaks apart?
