WebApr 6, 2024 · 5) As the rate of disappearance of ammonia is equal to the rate of formation of nitric oxide we can say that the rate of disappearance of ammonia is − 3 ⋅ 2 × 10 − 3 mol L − 1 S − 1. The rate of disappearance value is always negative as the concentration of reactant gets consumed in the reaction. The rate of appearance value is ... WebMay 21, 2024 · roshnirajeevsl Answer: Thus, the greatest rate of disappearance is shown by O₂. Explanation: The rate of a reaction is equal to the change in concentration divided by the time interval in which the change has taken place. As the concentration of reactants decreases, a negative sign is used to express the rate of reaction in terms of reactants.

WebFeb 12, 2024 · a) From the equation stoichiometry, Δ [H 2 O] = 6/2 Δ [N 2 ], so the rate of formation of H 2 O is 3 × (0.27 mol L –1 s –1) = 0.81 mol L –1 s –1. b) 4 moles of NH 3 are consumed for every 2 moles of N 2 formed, so the rate of disappearance of ammonia is 2 × (0.27 mol L –1 s –1) = 0.54 mol L –1 s –1.
