At a certain temperature the rate of this reaction is second order in H3PO4 with a rate constant of 0.0395 M_1 ”5—1 : 2H3PO4 (aq) —>P205 (aq) +3H20 (09‘) Suppose a vessel contains H3P04 at a concentration of 0.180M Calculate how long it takes for the concentration of H3PO4 to decrease to 19.0% of its initial value. You may assume no other reaction is important. Round your answer to 2 significant digits. [I s [:IXIOD
