Some measurements of the initial rate of a certain reaction are given in the table below. [NL] [H.] initial rate of reaction 0.794M 1.67M 0.518 M/s 0.376M 1.67M 0.245 M/S 0.794M 5.07 M 4.77 M/s Use this information to write a rate law for this reaction, and calculate the value of the rate constant k. Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol. rate = * B B 0.0 k = Х 5 ?
Consider this reaction: 2H,PO, (aq) --P,0, (aq) + 3H,0 (aq) At a certain temperature it obeys this rate law. rate - (3.05 [H,PO.] Suppose a vessel contains H, PO, at a concentration of 0.360M. Calculate how long it takes for the concentration of H,PO, to decrease to 0.022 M. You may assume no other reaction is important. Round your answer to 2 significant digits.
