The gas NO reacts with H₂, forming N₂ and H₂O: 2NO(g) + 2H₂ (g) → 2H₂O (g) + N₂ (g) If A[NO]/At = -19.0 M/s under a given set of conditions, what are the rates of change of [N 2] and [H₂O]? Rate of change of [N₂]: Rate of change of [H₂O]: PRACTICE: Consider the following reaction: 2HBr (g) → H₂ (g) + Br2 (g) In the first 23.0 s of this reaction the of HBr dropped from 0.550 M to 0.457 M. Calculated the average rate (M.s-¹) of the reaction in this time interval. Express your answer using two significant figures. If the volume of the reaction in part (a) was 1.50 L. what amount of Br₂ (in moles) was formed during the 15.0 s of the reaction? Express your answer using two significant figures.
