order would you expect? b. Another possibility is that the reaction occurs through more than one step. For example, a possible mechanism involves one step in which the two CH3NC molecules collide, resulting Exercises 635 with the second-order differential rate law and derive the second-order integrated rate law. 116. The rate constant for the first-order decomposition of N,05(g) to NO,(g) and O2lg) is 7.48 × 10³ s¯ at a given temperature. a. Find the length of time required for the total pressure in a system containing N,O5 at an initial pressure of 0.100 atm to rise to 0.145 atm. -3 -1 b. Find the length of time required for the total pressure in a system containing N2O5 at an initial pressure of 0.100 atm to rise to 0.200 atm. c. Find the total pressure after 100 s of reaction. 117. Phosgene (CI2CO), a poison gas used in World War I, is formed by the reaction of Cl, and CO. The proposed mechanism for the reaction is: Cl2 2 Cl Fast, equilibrium Cl + CO CICO Fast, equilibrium CICO + Cl2 Cl2CO + Cl Slow What rate law is consistent with this mechanism? 118. The rate of decomposition of N,O3(g) to NO2(g) and NO(g) is monitored by measuring [NO2] at different times. The following tabulated data are obtained. [NO2](mol/L) 0.193 0.316 0.427 0.784

(e) QUESTION 22 What is the hydronium (H3O*) concentration of a solution with a hydroxide (OH-) concentration of 8.2 x 10-3? You can enter your answer in exponential notation. For example, 1.0x105 would be expressed as 1.0E-5 QUESTION 23 A student is trying to determine the concentration of an acetic acid (HC;H3O2) solution. They place 7.00 mL of the solution in a flask and titrate it with a 0.200 M NAOH solution.
