Question

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 x 10-9 N was needed to break a C – Si bond, estimate the bond enthalpy in kJ/mol. Assume that the bond had to be stretched by a distance of 2 x 10-10 m before it is broken.

Answer 1

$2.0×10^9N ÷2×10^-10 1.0×10^-1$
