The structure of tofacitinib with explicit carbon and hydrogen is the first attached picture.

The number of carbon atoms in tofacitinib are 16.

The molecular formula of tofacitinib is C_{16}H_{20}N_{6}O.

The structure of tofacitinib with all the filled hydrogen atoms is the second attached picture.

Consider the change given below. At constant pressure, is work done by the system on the surroundings? By the surroundings on th
alexira [117]

Answer : At constant pressure work is done by the system on the surroundings.

Explanation :

Work done : Any quantity that flows across the boundary of a system during a change in its state and it completely convertible into the lifting of a weight in the surroundings.

Formula for work done is:

w=-p_{ext}dV

Sign convention :

  • When volume expand then system work that means work done by the system.

w = (-ve)

  • When volume compress then surrounding work that means work done on the system.

w = (+ve)

The given reaction is:

Hg(l)\rightarrow Hg(g)

This is a evaporation process in which phase changes from liquid state to gaseous state at constant temperature.

At constant pressure, work depends only on volume.

In evaporation process, the volume expand that means work is done by the system on the surroundings.

Sign convention is, w = (-ve)

Thus, at constant pressure work is done by the system on the surroundings.
