WebActivation energy is a key criteria for the assessment of catalytic performance in WGS reactions. To date, some of the lowest activation energy values have been found for catalysts consisting of copper nanoparticles on ceria support materials, with values as low as Ea = 34 kJ/mol reported relative to hydrogen generation. WebWhat is the effect of catalyst on (i) Gibbs energy and (ii) activation energy of reaction? Q. The role of a catalyst is to change ..... . (a) Gibbs energy of reaction (b) enthalpy of …
