In a measurement of quantum efficiency of photosynthesis in green plants, it was found that 10 quanta of red light of wavelength \[6850\overset{o}{\mathop{A}}\,\] were needed to release one molecule of \[{{O}_{2}}\]. The average energy storage in this process for 1 mole \[{{O}_{2}}\] evolved is 112 kcal. What is the energy conversion efficiency in this experiment? \[[Given:1\,cal=4.18J;{{N}_{A}}=6\times {{10}^{23}};\] \[h=6.63\times {{10}^{-34}}Js]\]
