Photobromination of cinnamic acid to dibromocinnamic acid was carried out in blue light of wavelength 440nm at 35degree celsius using light intensity of 1.5 *10 power -3 joule per second. An exposure of 20 minutes produces a decrease of 0.075 millimoles of bromine. The solution absorb 80% of light passing through it. Calculate the quantum yield of the reaction.
