54. Solution to Chemistry Problem

2. During the photodecomposition of cumyl hydroperoxide C6H5(CH3)2COOH, the reaction mixture was irradiated with light λ=270 nm and a radiation intensity of 11*10-4 J/s. In 20 min, the amount of hydroperoxide decreased by 0.020 mmol. The solution absorbed 90% of the light passing through it. Calculate the quantum yield of the reaction.
