Product description
19. Calculate the thermal effect of the hydrogenation reaction C2H4 (g) H2 (g) \u003d C2H2 (g) at 1000 K, if under standard conditions it is 128 kJ, and the molar heat capacities are as follows:
СрC2H2=4.50 182*10-3Т-74.86*10-6Т2 J/(mol*K)
СрH2=27.28 3.26*10-3Т 0.502*105Т-2 J/(mol*K)
СрC2H4=4.20 154.59*10-3Т-81.09*10-6Т2 J/(mol*K)
