"different reaction pathways" is a correct and usable phrase in written English.
You can use it when you are referring to alternative courses of action. For instance, you could say "The chemical reaction could take three different reaction pathways depending on the conditions."
It is found that the discrete local reaction rates rather than the time-averaged reaction rates should be adopted when using the ISSA method for mechanism reduction due to large temperature difference and different reaction pathways in combustion at different simulation conditions.
Potentiodynamic, potentiostatic and adsorbate-stripping experiments show distinct kinetic isotope effects (KIEs), which differ significantly for different reaction pathways such as the formation of CO2, COad and of the precursor for COad formation, and finally the overall reactivity expressed by the Faradaic current.
This difference might be most readily interpreted by the different reaction pathways between organic matter and water.
Opening and closure of the ion pore follow different reaction pathways because the kinetics of channel opening and dark state recovery differ by many orders of magnitudes.
The degradation of organic micropollutants occurs via different reaction pathways.
Several different reaction pathways have been developed to prepare poly(1,3,4-oxadiazole)s [18].
The first part shows that the formation of Bi0.88Sm0.12FeO3 using the two synthesis methods followed a different reaction pathway on annealing the powders.
The ORR activity is proposed to originate from a different reaction pathway due to coordinatively unsaturated Mn3+ ions on the surface of α-Mn2O3, which act as active centers for associative adsorption and reduction of molecular O2.
Note that the differences regarding the depicted proposed pathways in Fig. 17 and 20 reflect different suggested hypotheses and not an intrinsically different reaction pathway of HGDOs and GDOs).
Lin et al. showed in their study that the weak acid sites that form during phosphatation prefer a different reaction pathway to strong acid sites, which leads to higher yields of propylene.
Multiple and recent proposals contemplate a perturbed conformation of the ternary complex and/or a different reaction pathway may be engaged by a mismatched dNTP incorporation in DNA polymerases (3, 34, 37− 40).
