Students are trying to calculate the heat of reaction for the following target reaction. A + 3B 3C + 2D They find the heat of reactions for the two reactions as shown. A + 2B C + D AH = 20 kJ B → 2C + D AH-45 kJ When the students used Hess's Law correctly, what is the heat of reaction for the target reaction? +65 kJ O-25 kJ +25 kJ O-65 kJ
