Find ΔH for C₃H₈ (g)+ 6 H₂O (g)→ 3 CO₂ (g)+ 10 H₂ given C₃H₈ (g)+ 3 H₂O (g)→ 3 CO (g)+ 7 H₂ (g)ΔH = 499 kJ CO (g)+ H₂O (g)→ CO₂ (g)+ H₂ (g)ΔH = -41 kJ

Question

Quizplus · Accepted Answer

376 kJExplanation: The given reactions can be manipulated to find the ΔH for the target reaction. The first reaction is used directly, and the second reaction is multiplied by 3 to match the products and reactants of the target reaction. Adding the ΔH values accordingly (499 kJ + 3*(-41 kJ)) gives 376 kJ.
