a, Apparent activation energy (Ea) of the overall acetylene hydrogenation reaction. b, Measured KIE (H2/D2) on the acetylene hydrogenation reaction. Filled symbols, H2; empty symbols, D2. c, Hydrogen-splitting activation energy obtained from the HD formation rates. d, Activation energy of the hydrogen-cleavage process.
