A rigid container contains a mixture of 2 moles of a monoatomic gas with 1 mol of a polyatomic gas at a temperature of 3000 K. You then heat the mixture by supplying 39907.2 J of heat. At the end of the process, the mixture is at a temperature of 3600 K. If at 3000 K the translational as well as the 3 rotational degrees of freedom of the polyatomic gas are already activated, how many vibrational degrees of freedom does it have activated in this temperature range? (assume that the number of degrees of freedom does not change during the process) If necessary, consider: R = 8.314 J/mol∙K 1 cal = 4.19 J kb =1,38 x 10⁻²³ m² kg s⁻² K⁻¹

Question
A rigid container contains a mixture of 2 moles of a monoatomic gas with 1 mol of a polyatomic gas at a temperature of 3000 K. You then heat the mixture by supplying 39907.2 J of heat. At the end of the process, the mixture is at a temperature of 3600 K. If at 3000 K the translational as well as the 3 rotational degrees of freedom of the polyatomic gas are already activated, how many vibrational degrees of freedom does it have activated in this temperature range? (assume that the number of degrees of freedom does not change during the process)
If necessary, consider:
R = 8.314 J/mol∙K
1 cal = 4.19 J
kb =1,38 x 10⁻²³ m² kg s⁻² K⁻¹
