Chapter 4, Problem 4C.1E

Interpretation Introduction

Interpretation:

The gaseous compound having higher molar heat enthalpy among $\text{NO}$ and ${\text{NO}}_{\text{2}}$ has to be predicted.

Concept Interpretation:

Molar heat capacity is an intensive property and it’s the amount of heat required by one mole of substance to raise its temperature by one Kelvin.  Molar heat capacity of a substance depends upon its degree of freedom.  The intrinsic physical property of a substance that is required to measure the quantity of heat energy needed to change the temperature of the substance by a given quantity is known as heat capacity.
