Question: Which of the following expressions is correct to calculate enthalpy of a reaction?...

Which of the following expressions is correct to calculate enthalpy of a reaction?

A

ΔHreaction=∑ΔfHreactan⁡ts−∑ΔfHproducts\Delta H_{reaction} = \sum\Delta_{f}H_{reac\tan ts} - \sum\Delta_{f}H_{products}

B

ΔHreaction=∑B.E.products−∑B.E.reactan⁡ts\Delta H_{reaction} = \sum B.E._{products} - \sum B.E._{reac\tan ts}

C

ΔHreaction=∑B.E.reactan⁡ts−∑B.E.products\Delta H_{reaction} = \sum B.E._{reac\tan ts} - \sum B.E._{products}

D

ΔHreaction(vfHkfØ;k)=ΔH1×ΔH2×ΔH3....\Delta H_{reaction(vfHkfØ;k)} = \Delta H_{1} \times \Delta H_{2} \times \Delta H_{3}....

Answer

ΔHreaction=∑B.E.reactan⁡ts−∑B.E.products\Delta H_{reaction} = \sum B.E._{reac\tan ts} - \sum B.E._{products}

Explanation

Solution

: $\Delta H_{reaction} = \sum B.E.{reac\tan ts} $$$- \sum B.E.{products}$$
