A mixture of NO2 and NO4 reaches equilibrium relatively quickly over a wide range of temperatures. It was proposed to use such a mixture as a heat transfer substance having a high effective specific heat, (∂H/∂T)p.

Evaluate the effective specific heat of the mixture at 100 kPa, 27°C, and 100°C. Repeat the calculations for pressure of 1.0 MPa. Assume the gases are ideal, where k = 1.25 for NO2 and k = 1.20 for NO₄.
