Chemistry The first excited electronic energy level of the helium atom is 3.13 ✕ 10−18 J above the ground level.

That is, at what temperature will 5.0% of the population be in the first excited state?
If HO2 and HO4H were perfect gases, and vibrational motion of the molecules was ignored, what would the value of Cp be? Plot the heat capacities of each species over the range 200 K < T < 400 K.

(I have the equations for Temperature dependent entropies and heat capacities for both molecules plus their enthalpies of formation values at 298.15K. I am wondering how I would begin to solve this problem.)

A linear molecule may rotate about two axes. If the molecule consists of N atoms, then there are 3N- 5 vibrational modes. Use the equipartition theorem to estimate the total contribution to the molar internal energy from translation, vibration, and rotation for (a) carbon dioxide, CO2, and (b) dibromoethyne, C2Br2, at 2000 K. In contrast, a nonlinear molecule may rotate about three axes and has 3N- 6 vibrational modes. Estimate the total contribution to the molar in ternal energy from translation, vibration, and rotation for (c) nitrogen dioxide, NO2, and (d) tetrabromoethene, C2Br4,at 2000 K. In each case, first assume that all vibrations are active; then assume that none is.
A sample of methane of mass 45.00 g initially occupies 13.11 L at 310.0 K. Calculate the work done when the gas expands isothermally and reversiblly until its volume increases to 17.41 L. 1 Torr = 133.33 Pa; MW of methane = 16.04 g/mol and R=8.3145 J/K mol. W = J. 4 sig. fig.
The French chemists, Pierre L. Dulong and Alexis T. Petit, noted in 1819 that the molar heat capacity of many solids at ordinary temperatures is proportional to the number of atoms per formula unit of the solid. They quantified their observations in what is known as Dulong and Petit's rule, which says that the molar heat capacity, Cp, of a solid can be expressed as Cp = N. 3R where N is the number of atoms per formula unit and R is the universal gas constant. The observed heat capacity per gram of a compound containing rubidium and oxygen is 0.64 J · K¯¹ · g¯¹. Use Dulong and Petit's rule to determine the empirical formula of the compound. empirical formula: Rb5O Incorrect

The heat capacity of air is much smaller than that of liquid water, and relatively modest amounts of heat are therefore needed to change the temperature of air. This is one of the reasons why desert regions, though very hot during the day, are bitterly cold at night. The molar heat capacity of air at 298 K and 1.00 atm is approximately 21 J K−1 mol−1. Estimate how much energy is required to raise the temperature of the air in a room of dimensions 5.5 m × 6.5 m × 3.0 m by 10 °C. If losses are neglected, how long will it take a heater rated at 1.5 kW to achieve that increase, given that 1 W = 1 J s−1?

Part A: Methane at low temperatures Methane (CH4) is a tetrahedral molecule. Determine its specific heat capacity (at constant volume) at very low temperatures. Enter the value in units of the universal gas constant R. Hint: Remember that both vibrational and rotational modes are "frozen out" at low temperatures. What does the motion of a polyatomic gas molecule look like if it cannot vibrate or rotate? Cv,low = ? Part B: Methane at moderate temperatures Determine the specific heat capacity (at constant volume) of methane at moderate temperatures.
