Molar Heat Capacities

Postby stephanieyang_3F » Thu Jan 26, 2017 2:54 pm

I stumbled upon this concept in 8.29. Which would have a higher molar heat capacity: NO or NO2?

I've read from other posts that the more atoms present in the molecule, the higher the molecular complexity and thus the more possible bond vibrations that can absorb added energy. What if two molecules had the same complexity/number of atoms present but a few atoms were different. Would the heavier have the higher molar heat capacity?

The heat capacity in the book is derived from degrees of freedom, which does not consider mass.

I saw on the video on this and said that the ones with the most atoms will have the higher molar capacity.
