أنا تخصصي كيمياء عضوية وأدرس كيمياء فيزيائية متقدمة وهي صعبة علي بحكمي تخصصي وعندي أسئلة أود منكم مساعدتي في حلهاولكم جزيل الشكر والعرفان
what are relative population of the states of a two -level when the temperature is infinite?
2- calculate the translational partition function at a) 315 K and b ) 700 K Of a molecule of molar mass 120 g mol-1 in a container of volume 3.00 cm3 ?
3- An atom has double – fold degenerate ground level , a non – degenerate electronically excited level at 3500 cm-1 and a three – fold degenerate level at 5300 cm-1 .calculate the partition function of these electronic states at 2000 K ?
4- For a sample composed of the atoms in O3 , calculate the electronic contribution to the molar internal energy at 1850 K ?
5- At what temperature would the population of the first excited vibrational state of HCl be one – third of its population of the ground state ?
6- calculate the standard molar entropy of helium gas at a – 250K b – 300 K ?
7- Given the wave number of the vibration for Cl2 is 560 cm-1 , calculate the vibrational contribution to the entropy of the molecule at 500 K ?
8- If a system of distinguishable particles have only three non- degenerate energy levels separated by an energy that is equal to the value of kT at 10 K , calculate a- the ratio of populations in the states at 1K , 25K and 100 K b- the molar partition function , the molar energy and the molar entropy at 10 K ?
