The proposed steps for a catalyzed reaction

WebbThe catalytic conversion of CO2 to C2 products through the CO2 reduction reaction (CO2RR) offers the possibility of preparing carbon-based fuels and valuable chemicals in a sustainable way. Herein, various Fen and Co5 clusters are designed to screen out the good catalysts with reasonable stability, as well as high activity and selectivity for either C2H4 … WebbThe catalyst was separated by filtration under hot conditions after 20 min of reaction when yield was observed as 56.0 ± 0.4%. The reaction was continued without the catalyst for another 120 min. Observably, the yield slightly increased from 56.0 ± 0.4% to 57.6 ± 0.3%, which is an increase of 1.6% (see SI, Fig. S2).

WebbThe two-step mechanism below has been proposed for a reaction between nitrogen monoxide and molecular chlorine: Step 1: NO ( g) + Cl 2 ( g) ⇌ NOCl 2 ( g) fast Step 2: NOCl 2 ( g) + NO ( g) 2NOCl ( g) slow. Use this mechanism to derive the equation and predicted rate law for the overall reaction. WebbProfile X, because a catalyst minimizes the number of elementary steps required for a reaction to proceed. Profile Y, because there are three elementary steps in the reaction. Profile X, because the reverse activation energy is greater than the forward activation energy, which increases its rate.
