The ionization constant for water is 1.14*1015 at 0 °C and 9.60*10° 14 at 60.0 °C. Calculate the value of A S for the ionization of water over this temperature range, using any values you obtained in questions 19 and/or 20, and comment on its sign. O A specific value cannot be determined, but it should be negative, which would imply that there is an increase in order, which could result from the hydronium and hydroxide ions structuring the H20 molecules around them due to intermolecular forces.

Some measurements of the initial rate of a certain reaction are given in the table below. N2 H2 initial rate of reaction 0.849 M 1.92 M 88.0 M/s 0.849 M 4.04 M 390. M/s 0.359 M 1.92 M 15.7 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 - k0 k = 0 ?

The preparaons of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HCN is a weak acid. acids: 1 mol of NaOH is added to 1.0 L of a 0.7 M HCN bases: solution. other: 0.57 mol of HCl is added to acids: 1.0 L of a solution that is bases: I 1.5M in both HCN and NaCN. other: I Explanation Check 2021 McGraw.HiN Education.
