  1. *Intrinsic standard activation enthalpies, entropies and Gibbs free energies are determined according to transition state theory, see Supplementary Note 7. The error bars for ΔH° and ΔS° represent the 1−σ s.d., whereas the error bar for ΔG° represents the maximum error rounded up to the nearest integer.
