![## Chemical Kinetics Problem
Consider this reaction:
\[ 2HI(g) \rightarrow H_2(g) + I_2(g) \]
At a certain temperature it obeys the following rate law:
\[ \text{rate} = (0.0257 \, \text{s}^{-1}) [\text{HI}] \]
Suppose a vessel contains HI at a concentration of 0.180 \( M \). Calculate how long it takes for the concentration of HI to decrease by 83.0%. You may assume no other reaction is important.
Round your answer to 2 significant digits.
