Answer: The question has some details missing. Here is the complete question; An molecule adsorbed at one site on a surface. An oxygen molecule is adsorbed onto a small patch of the surface of a catalyst. It's known that the molecule is adsorbed on 1 of 576 possible sites for adsorption (see sketch at right). Calculate the entropy of this system. Round your answer to 3 significant digits.

Explanation:

The stefan boltzmaan constant for entropy is given by;

S = kInw we are given that 576 total possible sites in which O2 can get absorbed w = 576, k = 1.38 x 10-23J/k

plugging the values into the equation;

S = 1.38 x 10-23J/k X In (576)

Entropy of the system = 8.79 X 10-23J/k
