The standard enthalpies of combustion at 25°C of hydrogen gas, H2(g), n-butane – C4H10(g), 1-butene – C4H8(g), and 1,3-butadiene – C4H6(g), are –285.84 kJ, –2878.6 kJ, -2818.8 kJ and -2543.5 kJ, respectively. Calculate ∆H° for the following reactions. a. C4H6(g) + 2 H2(g) → C4H10(g) The net equation is: C4H8(g) + H2(g) → C4H10(g) ∆H°25°C = – 226.04 kJ
