Proposed reaction mechanism
Webb14 juni 2024 · First-principle methods can be used to explore the lattice constants, electronic structures, carrier mobility and diffusion lengths of photocatalyst, understand the reaction mechanism, and further predict new halide perovskite-based photocatalyst ( Catlow et al., 2010; Luo and Daoud, 2015; Yu, 2024 ). WebbThe elementary steps of a proposed reaction mechanism are represented below. Step 1: 2 NO2 (0) -- NO (g) + NO3 (0) (slow) Step 2: NO3 (0) + CO (g) + NO2 (g) + CO2 (0) (fast) Which of the following is the rate law for the overall reaction that is consistent with This problem has been solved!
