The formation of Co2(CO)64-NBD) from Co2(CO)8 and NBD is a reversible endothermic reaction: Co2(CO)8 + NBD {A figure is presented} Co2(CO)64-NBD) + 2CO; ΔH0 14.9 ± 0.7 kcal mol-1 In the forward reaction the carbon monoxide evolution is of first order in both Co2(CO)8 and NBD and of minus first order in CO. The carbon monoxide uptake in the reverse reaction is first order in both Co2(CO)64-NBD) and CO. The temperature dependence of the equilibrium constant K, and of the rate constant for the forward reaction kCO between 25 and 45°C is represented by log10 K = (7.41 ± 0.48) - (3259 ± 147)/T (K in M) and log10 kCO = (18.30 ± 1.75) - (7054 ± 540)/T (kCO in s-1).
