Q15(a). Rate of formation of CO from the quantum yield
On irradiation of propionaldehyde at 30 °C with light of 302 nm, the quantum yield of formation of CO is found to be 0.54. The intensity of incident light is 15000 erg s⁻¹. Find out the rate of formation of CO.
Answer in brief
Rate of formation of CO = 1.23 × 10¹⁵ molecules s⁻¹ = 2.04 × 10⁻⁹ mol s⁻¹ (all incident light taken as absorbed).
