35CI2 has a harmonic vibrational wavenumber of 559.7 cm-1. Without precise calculations, but noting all assumptions and reasoning, sketch a labelled-axis graph of the total molar heat capacity of 35CI2 between 300 K and 2000 K.

(c) Consider atomic oxygen gas at the temperature of 298.15 K. (i) Calculate its heat capacity at constant volume, assuming that the first two excited states have a non-negligible population. (ii) What would happen to the heat capacity at constant volume when the temperature increases to 1000 K? Discuss qualitatively. Data: The term symbols of the ground and first two excited states are (in increasing order): 3P2, 3P₁ and ³Po; AV₁-2 = 158.5 cm¹; AV₁ = 226.5 cm-1 AV1→2 1-3

Part A Determine the total molecular partition function for gaseous H2O at 1000. K confined to a volume of 2.20 cm³ . rotational constants for water are BA = 27.8 cm-1, BB = 14.5 cm-1, and Bc = 9.95 cm-1. The vibrational frequencies are 1615, 3694, and 3802 cm-. The ground electronic state is nondegenerate. (Note: the Avogadro's constant NA The 6.022 x 1023 mol-1). Express your answer to three significant figures.
