Stoichiometry - FIITJEE REE

Oxalic acid decomposes in presence of UO_2²⁺ & loses its property.

This is used in estimating the amount of decomposed acid & quantum efficiency of the process

Here efficiency = 50 % . 1L of 0.005 M oxalic acid solution was irradiated with light in the presence of UO_2²⁺ ION.

20 mL of the irradiated solution on titration required 25 mL of 0.005 N KMnO₄ solution.

How many photons are absorbed per decond if the solution was irradiated for 10.5 min???
