t (s) What is the half life of the reaction? 0.8 Use this graph to answer the following questions: Round your answer to 2 significant digits. Suppose the rate of the reaction is known to be first order in NH3. 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 NH3 in the engineer's reaction vessel after 1.60 seconds have passed. Assume no other reaction is important, and continue to assume the rate is first order in NH3. Round your answer to 2 significant digits. 11/2=0s k = 0 [NH, J-Dư 0.0 X 2

Question
A chemical engineer is studying the rate of this reaction. 2NH3 (g) →N₂(g) +3H₂ (g) She fills a reaction vessel with NH₂ and measures its concentration as the reaction proceeds. Here's a graph of her data: [NH3](M) 0.20- 0.15 0.10- 0.05- 0. 0.2 0.4 0.6 t (s) 0.8 Use this graph to answer the following questions:
