What is the formula of enthalpy in terms of bond energy of reactant and product?
Answers
Answer:
Bond energies (bond enthalpies) can be used to estimate the heat of a reaction (enthalpy change of a reaction, ΔHo). ⚛ ΔHo(reaction) = sum of the bond energies of bonds being broken - sum of the bond energies of the bonds being formed.

Explanation:
To find how much energy is released when these bonds are formed, we'll need to multiply each bond enthalpy by −1 . Also, since two new C−Hstart text, C, end text, minus, start text, H, end text bonds are formed, we'll need to multiply the C−Hstart text, C, end text, minus, start text, H, end text bond enthalpy by 2.
Answer:
Enthalpy (H) is the sum of the internal energy (U) and the product of pressure and volume (PV) given by the equation: H=U+PV. When a process occurs at constant pressure, the heat evolved (either released or absorbed) is equal to the change in enthalpy.
