An oxygen o2 molecule is adsorbed on a patch of surface (see sketch at right). this patch is known to contain 484 adsorption sit

es. 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 729 adsorption sites are now available for the molecule. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.

Answer:

The change in entropy is 5.65\times 10^{-24} J/K.

Explanation:

The entropy can be determined from Boltzmann equation of entropy:

S=K_b\ln w

S = Entropy of the system

K_b=1.38\times 10^{-23} J/K

w = Number of microstates

1) Number of adoption sites = 484

w = 484

S_1=1.38\times 10^{-23} J/K\ln 484=8.5312\times 10^{-23} J/K

2) Number of adoption sites = 729

w =729

S_2=1.38\times 10^{-23} J/K\ln 729=9.0965\times 10^{-23} J/K

Change in entropy =S_2-S_1

\Delta S=9.0965\times 10^{-23} J/K-8.5312\times 10^{-23} J/K=5.653\times 10^{-24} J/K

The change in entropy is 5.65\times 10^{-24} J/K.

We have Boltzmann's equation S = k ln W 
Boltzmann's constant k = 1.381 x 10^-23 J/K
 W = Number of absorption sites
 At W = 484, Entropy S1 = 1.381 x 10^-23 ln 484 = 8.537 x 10^-23 J/K
 At W = 729, Entropy S2 = 1.381 x 10^-23 ln 729 = 9.103 x 10^-23 J/K
 Change of Entropy = S2 - S1 = 0.566 x 10^-23 J/K

Assume that a raindrop has a volume of 3.48 cm3. If you had an Avogadro’s number of raindrops that just filled a cubic box. What
N76 [4]
Answer is: <span>edge of the length of the box measured is 1280,57 kilometers.
</span>V(raindrop) = 3,48 cm³.
V(cubic box) = 3,48 cm³ · 6,023·10²³.
V(cubic box) = 2,1·10²⁴ cm³.
V(cubic box) = 2,1·10²⁴ cm³ ÷ 10¹⁵.
V(cubic box) = 2,1·10⁹ km³.
r(cubic box) = ∛2,1·10⁹ km³.
r(cubic box) = 1280,57 km.
