5. Calculate the thermal effect of the same reaction (according to the variant number in Table 1) at 400 K. The heat capacity in J/(mol K) is expressed by the equation СР0=а bT c΄/Т2 or СР0=a bT cT2. Take the coefficients a,b,c,c΄ from Table 2.
Note: in table 2, you should pay attention to the factors of the coefficients a, b, c, c΄. For example, the entry b·103=0.67 (for chlorine) means that the true value of the coefficient b=0.67/103= 0.67·10-3.
4NO 6H2Ogas = 4NH3 5O2
