Here is a gas-phase isotopic exchange reaction: H2 + D2 --> 2HD (D is deuterium and has a mass of 2 AMU) . The vibrational and rotational energies of products and reactants have these temperature parameters: H2(Q vib = 6215, Q rot = 85.3), D2 (Q vib = 4394, Q rot = 42.7), HD (Q vib = 5382, Q rot = 64.0) Calculate the ratio of vibrational partition functions (products/reactants). Is this ratio going to have a temperature dependence? If...
