Calculate ΔH_rxn

Initial temperature

150

° C

$ \mathrm{ C_{2} H_{2} + H_{2} \longrightarrow C_{2} H_{4} } $

Choose a temperature, then click "Calculate ΔH_rxn" to begin

$$ \int_{500^{ \circ }}^{25^{ \circ }} c_{p, r} dT $$

$$ + \Delta H_{rxn}^{^\ominus} $$

$$ + \int_{25^{ \circ }}^{500^{ \circ }} c_{p, p} dT $$

$$ = -183.8 \; \mathrm{ \frac{ kJ }{ mol } } $$
