How will you calculate reaction enthalpy from data on bond enthalpies?
Answers
Answer:
Use the formula ∆H = m x s x ∆T to solve.
Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve
Explanation:
Bond energies (bond enthalpies) can be used to estimate the heat of reaction (enthalpy of reaction). A chemical reaction will be endothermic if the energy absorbed to break bonds in the reactant molecules is greater than the energy released when bonds are formed in the product molecules.
In symbols, the enthalpy, H, equals the sum of the internal energy, E, and the product of the pressure, P, and volume, V, of the system: H = E + PV. According to the law of energy conservation, the change in internal energy is equal to the heat transferred to, less the work done by, the system.
Explanation:
Use the formula∆H=m×s*∆T to solve
