In a pulse radiolysis experiment, H atoms are suddenly created in liquid ethanol (density 0.79 g cm) containing 8 mM ethene. The initial concentration of H atoms falls to half its value in 1.8 ns. Two different radical products are detected by ESR, CH;CH2 and CH;ĊHOH, in the ratio 1:3. 3. H+ CH2=CH2 → CH3CH2 (1) H+ CH3CH2OH → H2 + CH;CHOH (2) Calculate the pseudo-first-order rate constant for H decay, and thence determine the second-order rate constants for reactions (1) and (2).
