Introduction:
Energy is that physical identity that cannot be seen but it is present and can be felt. Without energy, nothing is possible to exist in this world. It is the most basic requirement of everything organism. It provides the capability to do work. It is totally different from

In the present experiment, w, which consists mainly of the work of stirring, can be neglected' and Eq. (2) then becomes AUc = 0 (3) Since the energy Change is independent of path, one has AU = AU + J Co CdT (4) Since the temperature change is small, it is usually valid to consider C to be constant, so that the integral becomes equal to C(T2 - T1). One then obtains AUT1= -C(T2 - T1) (5) It may be observed that a temperature rise corresponds to a negative AUT1, that is, to a decrease in energy for the imagined isothermal process. The next step is to calculate AU,° from AUT1. Although the energy is not sensitive to changes in pressure, the correction to standard states, called the Washburn correction,…arrow_forward

Neither are part of the "net equation" for the reaction. Both contain covalent bonds are in the process of breaking and/or forming. Both are part of every chemical reaction.
