🤓 Based on our data, we think this question is relevant for Professor Holland's class at SDSU.
Given the standard enthalpy changes for the following two reactions:
4C (s) + 5H2 (g) → C4H10 (g) ΔH° = -125.6 kJ
C2H4 (g) → 2C (s) + 2H2 (g) ΔH° = -52.3 kJ
what is the standard enthalpy change for the reaction:
2C2H4 (g) + H2 (g) → C4H10 (g) ΔH° = ?
