The quantum yield for decomposition of HI id 0.2 .In an experiment 0.01 moles of HI are decomposed .
Find the number of photons absorbed.

An important parameter of a photochemical reaction is the quantum effeiciency or quantum yield (phi) which is defined as phi=("moles of the substance reaction")/("moles of photons absorbed") Absorption of UV radiation decompose acetone according to the reaction (CH_(3))_(2)COoverset(hv)(rarr)C_(2)H_(6)+CO If quantum yield in 0.8 then rate of formation of C_(2)H_(6)(mol//s) is :
