G°rxn should read +1.37 kcal mol-1 and not -1.42 kcal mol-1. As a result H°acid for benzocyclobutanone is 359.8 kcal mol-1 and not 360.3 kcal mol-1.Additions and corrections

On page 2391, line 12, G°rxn should read +1.37 kcal mol-1 and not -1.42 kcal mol-1. As a result H°acid for benzocyclobutanone is 359.8 kcal mol-1 and not 360.3 kcal mol-1.
In eqn. (16), H°rxn = -7.4 ± 5 kcal mol-1 not -6.9 ± 5 kcal mol-1. Benzocyclobutenone is a stronger acid than cyclobutanone by 7.4 kcal mol-1 rather than 6.9 kcal mol-1 as originally reported.
In eqn. (17), H°rxn = -9.6 ± 3 kcal mol-1 not -10.1 ± 3 kcal mol-1. 1-Phenylpropan-2-one is more acidic than benzocyclobutenone by 9.6 ± 3 kcal mol-1 rather than 10.1 ± 3 kcal mol-1 as originally reported.
