A single oxygen molecule (O2) is adsorbed on a patch of

A single oxygen molecule (O2) is adsorbed on a patch of surface (see sketch). This patch is known to contain 221 adsorption sites. The O2 molecule has enough energy to move from site to site, so it could be on any one of them. An U2 molecule aasordea at one site on a surface. Suppose part of the surface becomes inaccessible so that the entropy of the system changes by 1.491023J/K. How many sites remain accessible to the O2 after this entropy change? S=kBlnWS=SfinalSinitial=kBlnWfinalkBlnWinitialkB=1.381023KJ Report your answer to the nearest whole number. Example: 100
