2C(s) + 2H2(g) → C2H4(g): ΔH = +52.4 kJ/mol

Which statement about this reaction is correct? (3 points)
52.4 kJ of energy are released for every mole of carbon reacted.
52.4 kJ of energy are absorbed for every mole of carbon reacted.
26.2 kJ of energy are released for every mole of carbon reacted.
26.2 kJ of energy are absorbed for every mole of carbon reacted.

Respuesta :

Answer:

26.2 KJ of energy are absorbed for every mole of carbon reacted

Explanation:

Since the enthalpy change (∆H) is positive the reaction is endothermic, that is, one mole ofcarbon absorbs 26.2KJ of energy from the surrounding
