In 1998 scientists using a special type of electron microscope were able to measure the force needed to break a single chemical bond. If \(2.0\times10^{29}\mathrm{\ N}\) was needed to break a \(\mathrm{C}―\mathrm{Si}\) bond, estimate the bond enthalpy in kJ/mol. Assume that the bond had to be stretched by a distance of 2 Å \((2 \times 10^{-10} \mathrm{ m})\) before it is broken.

In 1998 scientists using a special type of electron microscope were able to measure the force needed to break a single chemical bond. If \(2.0\times10^{29}\mathrm{\ N}\) was needed to break a \(\mathrm{C}―\mathrm{Si}\) bond, estimate the bond enthalpy in kJ/mol. Assume that the bond had to be stretched by a distance of 2 Å \((2 \times 10^{-10} \mathrm{ m})\) before it is broken.
ANSWER:Step 1 of 2
Here, we are calculate the C-Si bond enthalpy.
Bond enthalpy :
It is the change required to break a particular bond in 1 mole of gaseous molecules.
