Embarking on the fascinating journey of chemical kinetics, my latest exploration delves into the intricacies of reaction rates and stoichiometry, with a spotlight on the decomposition of ammonia (NH₃). Unraveling the molecular ballet of the equation 2NH₃(g) → N₂(g) + 3H₂(g), we decipher the role of stoichiometric coefficients in shaping the rate of change of reactants and products. In this blog post, we demystify the significance of A[NH₃]/Δt, the rate of change of ammonia, connecting the dots between the known rate A[H₂]/Δt of 0.030 mol/s. Join me as we navigate through the elemental principles governing reaction kinetics, shedding light on the captivating world of chemical transformations.
