 The hydrolysis activation energies calculated from the temperature dependencies of the fitted values of rate constants, K=1/t0, vary between 20 and 37 kJ/mol. We note that the presented values are just rough estimations due to rather poor fitting of the data with Eq. 5 (see Figure in Supplementary Information). On our opinion, this is caused by the underestimation of the measured hydrogen evolution rates above 1.5 Nl/(min g) that takes place at the higher temperature (75˚C) and/or the higher concentrations of the organic acids.
