Consider this reaction:
2H, PO₂ (aq)-P₂O, (aq) + 3H₂O (aq)
At a certain temperature it obeys this rate law.
rate - (0.221 s¹)[H₂PO4]
Suppose a vessel contains H₂PO, at a concentration of 1.30 M. Calculate how long it takes for the concentration of H₂PO4 to
decrease to 15.0% of its initial value. You may assume no other reaction is important.
Round your answer to 2 significant digits.
