25. In a cubic container with sides 1 cm in length that contains 1 atm of Ar at 298 K. What is the average velocity of Ar approximately? Mass of Ar = 40 (A) 2.0 ×102 (B) 2.0 x103 (C) 4.0 x102 (D) 4.0 ×103 (E) 6 x102 m s¹.

24. A reaction is catalyzed by the bromide ion shown below: Br H+ + HNO2 + C6H5NH2 C6HsN2+ + 2H2O. A proposed mechanism is (1) H++ HNO2 ≈ H2NO2+ (2) H2NO2++Br→ ONBr + H2O (3) ONBr + C6H5NH2 → C6H5N2+ + H2O + Br Symbol kn denotes the rate constant for the step n. (A) Assume that the second step is the rate-limiting. The rate law is k2[H2NO2*][Br_] (B) Assume that the second step is the rate-limiting. The rate law is k2[H+][HNO2][Br] (C) Assuming quasi-steady-state approximation, the rate law is k2[H2NO2+][Br]. (D) Assuming quasi-steady-state approximation and excess [Br ], the rate law is k1[H'][HNO2] (E) Assuming quasi-steady-state approximation and excess [Br], the rate law is (k/k-1) k2[H+][HNO2][Br]

23. Molecular oxygen populating the excited singlet state (¹Ag) can relax to the ground triplet state (32g) by emitting a 1280 nm (= 7812.5 cm¹) photon. (A) The partition function consist of these electronic states is q = 1 + 3e~B(7812.5), ẞ = 1/RT in (cm¹)-1. (B) Molecular oxygen a homonuclear diatom, shows no infared vibrational spectra. Hence, its vibrational partition function is zero. (C) The translational partition function of molecular oxygen is function of volume. (D) The rotational partition function of molecular oxygen is function of volume. (E) None of above is correct.
