A chem raduate student is studying the rate of this reaction! 2HI (g) → H₂(g) + 1₂ (8) He fills a reaction vessel with HI and measures its concentration as the reaction proceeds: time (seconds) 0 1.0 2.0 3.0 4.0 [HI] 0.0500M 0.0186M Explanation 0.0115 M 0.00827 M 0.00647 M Use this data to answer the following questions. Write the rate law for this reaction. Calculate the value of the rate constant k. Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. Check rate = k k= O X 4.

Suppose une formation of nitryl fluoride proceeds by the following mechanism: rate constant step elementary reaction 1 NO₂(g) + F₂(g) → NO₂F(g) + F(g) k₁ F(g) + NO₂(g) → NO₂F(g) k₂ Suppose also k₁>k₂. That is, the first step is much faster than the second. 2 Write the balanced chemical equation for the overall chemical reaction: Write the experimentally- observable rate law for the overall chemical reaction. Note: your answer should not contain the concentrations of any intermediates. & Express the rate constant k for the overall chemical reaction in terms of K₁, K₂, and (if necessary) the rate constants k.₁ and k.2 for the reverse of the two elementary reactions in the mechanism. Explanation Check 0 rate = k k = 0 010
