An oxygen (O2) molecule is adsorbed on a patch of surface (see sketch at right). This patch is known to contain 324 adsorption sites. The (O2) molecule has enough energy to move from site to site, so it could be on any one of them. Suppose additional surface becomes exposed, so that 400 adsorption sites are now available for the molecule. Calculate the change in entropy. One way an O, molecule could be adsorbed on a patch of surface with 16 sites Round your answer to 3 significant digits,

Respuesta :

The change in entropy is 2.91 x 10-24 J/K

For an ideal gas,

The entropy of a molecule, S = KB ln(W)

KB – Boltzmann constant (1.38065 x 10-23 J/K)

W – Equivalent microstates of the molecule.

Winitial = 324

Wfinal = 400

Sfinal – Sinital = KB ln(Wfinal) - KB ln(Winital)

ΔS = KB ln(Wfinal / Winital)

= (1.38065 x 10-23 J/K) * ln(400/324)

= 2.91 x 10-24 J/K

In the ideal gas law, the temperature of the hydrogen gas is determined if the volume and pressure of the gas are known.
