Hydrogen gas will react with either acetylene, C,H2, or ethylene, C,H4, gas. The thermochemical equations for these reactions are provided below. Calculate the AH° of the conversion of acetylene into ethylene by hydrogen gas. C2H2(g) + 2H½(g) → CH5 AH° = -311 kJ C2H6 → C2H4(g) + H2(g) AH° = 136 kJ Round your answer to 0 decimal places.
