A chemical engineer is studying the rate of this reaction. H,CO, (aq) → H,O(aq)+CO, (aq) He fills a reaction vessel with H₂CO3 and measures its concentration as the reaction proceeds. Here's a graph of his data: (W) [²00³H] 03. ! (S)
Use this graph to answer the following questions: What is the half life of the reaction? Round your answer to 2 significant digits. Suppose the rate of the reaction is known to be first order in H₂CO3. Calculate the value of the rate constant k. Round your answer to 2 significant digits. Also be sure you include the correct unit symbol. Predict the concentration of H₂CO3 in the engineer's reaction vessel after 10.5 seconds have passed. Assume no other reaction is important, and continue to assume the rate is first order in H₂CO3. Round your answer to 2 significant digits. 11/2 = 0s k = [H₂CO₂] = M
