A chemical engineer is studying the rate of this reaction. 2HI (g) → H₂(g) + 1₂ (8) She fills a reaction vessel with HI and measures its concentration as the reaction proceeds. Here's a graph of her data: [HI] (M) 0.2 0.15 0.02 0.04 0.06 What is the half life of the reaction? t (s) Use this graph to answer the following questions: 0.08 Round your answer to 2 significant digits. Suppose the rate of the reaction is known to be first order in HI, Calculate the value the rate constant k Round your answer to 2 significant digits. Also be sure you include the correct unit symbol. Predict the concentration of HI in the engineer's reaction vessel after 0.140 seconds have passed. Assume no other reaction is important, and continue to assume the rate is first order in HI, Round your answer to 2 significant digits. 1/2 = 0 s k = 0 [HI] = M 0.0
