2. The constant pressure molar heat capacity of nitrogen, N2, has been found to vary with temperature according to the relation, Cp.m /] K¯²mol-1 = a + bT + T2 with a = 28.58, b = 3.77 x 10-3 K-1 and c = -0.50 x 10° K² . (a) Graph the constant pressure molar heat capacity between 300OK to 1000K. (b) Comment on how your graph compares to plot at: https://webbook.nist.gov/cgi/cbook.cgi?ID=C7727379&Units=SI&Type=JANAFG&Plot=on#JANAFG (c) What is the change in enthalpy going from 300 K to 1000 K? Hint: dH = Cp(T)dt.
