WebQuestion: Consider the following balanced chemical reaction: 2 MnO_4^- (aq) + 5 H_2O_2 (aq) + 6 H^+ (aq) rightarrow 2 Mn^2+ (aq) + 5 O_2 (g) + 8 H_2O (l) a) A student wrote … WebThe rate law for the reaction 2 H2 + 2 NO \to → N2 + 2H2O is rate = k [H2] [NO]^2. Which of the following mechanisms can be ruled out on the basis of the observed rate expression. Mechanism I. H2 + NO \to → H2O + N (slow) N + NO \to → N2 + O (fast) O + H2 \to → H2O (fast) Mechanism II H2 + 2NO \to → N2O + H2O (slow) N2O + H2 \to → N2 + H2O (fast)

WebA reaction was experimentally determined to follow the rate law, Rate = k [A] where k = 0.15 s-1. Starting with [A]o = 0.225M, how many seconds will it take for [A]t = 0.0350M? 12 s At 25°C the rate constant for the first-order decomposition of a pesticide solution is … WebFeb 12, 2024 · rate = k [ A] [ B] 2. This reaction is third-order overall, first-order in A, second-order in B, and zero-order in C. Zero-order means that the rate is independent of … cyber security m\u0026a 2016
The rate law for the reaction 2 H2 + 2 NO $\to$ N2 - Quizlet
WebA proposed mechanism for the oxidation of nitric oxide to nitrogen dioxide is shown below. 2 NO (g) ⇄ N 2 O 2 (g) fast, reversible step N 2 O 2 (g) + O 2 (g) → 2 NO 2 (g) slow step What rate law is consistent with this mechanism? Rate = k [N 2 O 2 ] [O 2] Rate = k [NO] [O 2] Rate = k [NO] 2 Rate = k [NO] 2 [O 2] Expert Answer 93% (30 ratings) WebA) The rate law cannot be determined from the information given. B) The rate law is; rate = k [H2S]2 [O2]. C) The reaction is second-order overall D) The rate law is; rate = k [H2S] [O2]. E) The reaction is third-order overall The rate law cannot be determined from the information given. Web2 N 2 O 5 → 4NO 2 + O 2 rate = k [N 2 O 5] BUT 2 NO 2 → 2NO + O 2 rate = k [NO 2]2 CAN’T predict these from equations!
