A chemical engineer is studying the rate of this reaction. H₂CO3(aq) → H₂O (aq) + CO₂(aq) She fills a reaction vessel with H₂CO3 and measures its concentration as the reaction proceeds. Here's a graph of her data: [H₂CO₂] (M) 0.2 0- 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 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 0.120 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. 4/2 = 0s k = [H₂CO₂] = M 00 0.0 X 00 S

A chemical engineer is studying the rate of this reaction. H₂CO3(aq) → H₂O (aq) + CO₂ (aq) She fills a reaction vessel with H₂CO and measures its concentration as the reaction proceeds. Here's a graph of her data: [H₂CO₂] (M) 0.8- 0.6- 0.4 0.2 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 H₂CO3. Calculate the value of the rate constant it. 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 0.120 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. 41/2 = 0 s k= [H₂CO₂] = M ロ・ロ X 00
