TLDR
In this article, the authors investigated carbon dioxide reforming of methane to synthesis gas using Ni catalysts in the temperature range of 500-850°C and showed that the overall reaction can be described by a Langmuir-Hinshelwood mechanistic scheme, assuming that methane dissociation is the rate determining step.About:

Isotopic and kinetic assessment of the mechanism of reactions of CH4 with CO2 or H2O to form synthesis gas and carbon on nickel catalysts
Junmei Wei,Enrique Iglesia +1 more
TL;DR: Turnover rates for forward reactions of CH 4/CO 2 and CH 4 /H 2 O mixtures were proportional to CH 4 pressure (5-450 kPa) and independent of the partial pressure of the CO 2 or H 2 O coreactants (5 −450 kPA), indicating that these reactions are mechanistically equivalent as discussed by the authors.

Dry reforming of methane over nickel catalysts supported on magnesium aluminate spinels
TL;DR: In this article, a co-precipitation method was used to support Ni-based catalysts for dry reforming of methane to synthesis gas, and the results showed that Ni/MgOγ-Al2O3 and Ni/Al 2O4 catalysts exhibit higher activity and better stability using a stoichiometric feed ratio (1:1).
