At a certain temperature this reaction follows second-orderkinetics with a rate constant of ·7.18M−1:s−1→2H3PO4aq+P2O5aq3H2Oaq Suppose a vessel contains H3PO4 at aconcentration of 0.640M. Calculate how long it takes for theconcentration of H3PO4 to decrease to 0.141M. You may assume noother reaction is important. Round your answer to 2 significantdigits.
