Question
A chemical engineer is studying the rate of this reaction.
He fills a reaction vessel with and measures its concentration as the reaction proceeds. Here's a graph of his data:
0.511.520204060801000
Use this graph to answer the following questions:
What is the half life of the reaction?
Round your answer to significant digits.
Suppose the rate of the reaction is known to be first order in . Calculate the value of the rate constant .
Round your answer to significant digits. Also be sure you include the correct unit symbol.
Predict the concentration of in the engineer's reaction vessel after seconds have passed.
Assume no other reaction is important, and continue to assume the rate is first order in .
Round your answer to significant digits.
