Question
Answer in two significant digits please.
Consider this reaction:
2H₂PO4 (aq) → P₂O5, (aq) + 3H₂O (aq)
At a certain temperature it obeys this rate law.
rate = (2.7 s ¹) [H₂PO₂]
Suppose a vessel contains H₂PO4 at a concentration of 0.740 M. Calculate the concentration of H₂PO4 in the vessel 1.00 seconds later. You may assume no
other reaction is important.
Round your answer to 2 significant digits.
