![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
H3PO4. 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 H3PO4 in the engineer's
reaction vessel after 2.50 seconds have passed.
Assume no other reaction is important, and continue to
assume the rate is first order in H3PO 4.
Round your answer to 2 significant digits.
