Clustering reactions

C₂H₅O^- +  = C₃H₆F₃O^-

By formula: C₂H₅O^- + CHF₃ = C₃H₆F₃O^-

C₂H₅O^- +  = (C₂H₅O^- • )

By formula: C₂H₅O^- + CH₄O = (C₂H₅O^- • CH₄O)

Free energy of reaction

(C₂H₅O^- • 4294967295) +  = C₂H₅O^-

By formula: (C₂H₅O^- • 4294967295C₂H₄O) + C₂H₄O = C₂H₅O^-

C₂H₅O^- +  = (C₂H₅O^- • )

By formula: C₂H₅O^- + C₂H₆O = (C₂H₅O^- • C₂H₆O)
