Assume that for ¹H³5Cl molecule the rotational quantum number J is 11 and vibrational quantum number n = 0. The isotopic mass of ¹H atom is 1.0078 amu and the isotopic mass of 35 Cl atom is 34.9688 amu, k = 516 N·m-¹, and xe = 127.5 pm. Compare the rotational energy with kBT at 297 K. Express your answer to three significant figures. 17 ΑΣΦ Erotational КВТ = ?

A standard sample of Argon gas is 22.4L, 1.00atm, 1.00mol, 273.15K.   In the right setups excited gas can be tricked into using heat and giving away photons of light.  If the sample gave off 0.01mol of 3,634nm light by converting thermal energy into those photons find the new final temp of the gas. SAr = 0.52J/gK

The density of gray and white tin are 5.77×10^3 kg/m3 and 7.37×10^3 kg/m3. The latent heat for the transition between gray and white tin is 2.20×10^3 J/mol. The atomic weight of tin is 118.7. Calculate the slope of the tangent of the coexistence curve of gray and white tin at T=386 K.

The rotational constant for the molecule 1H35Cl is B = 10.60 cm-1. Using Boltzmann statistics, determine the most likely rotational state J that such a molecule would be expected to have at a temperature of 300 K.

Question 16 The most intense peak in a pure rotational spectrum of a gas of a diatomic molecule with rotational constant 4.560 cm¹¹ was found to correspond to transitions out of the J = 10 rotational energy level. Assuming that the molecule behaves as a rigid rotor, estimate the temperature (in K) at which this spectrum was measured. (Give your answer to at least 3 significant figures.)

5. For carbon monoxide at 298K, determine the fraction of molecules in the rotational levels for J=0, 5, 10, 15, and 20. The rotational constant (B) is 3.83x10^-23 Joules.
