An oxygen (O₂) molecule is adsorbed on a patch of surface (see sketch at right). This patch is known to contain 400 adsorption sites. The (0₂) molecule has enough energy to move from site to site, so it could be on any one of them. Suppose part of the surface becomes inaccessible, so that only 169 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. B 0.8 04 X H Using the thermodynamic information in the ALEKS Data tab, calculate the standard reaction entropy of the following chemical reaction: N₂ (g) + 3H₂(g) → 2NH, (g) Round your answer to zero decimal places. One way an O, molecule could be adsorbed on a patch of surface with 16 sites. X

Given the following propositions, indicate which or which are correct: When a catalyst is added to a system: I) The enthalpy change of the reaction becomes more negative, that is, the reaction becomes more exothermic and therefore faster . II) The Gibbs standard energy variation becomes more negative and consequently its speed increases. III) The equilibrium state is not modified. IV) The mechanism of the reaction is modified and therefore its speed increases.
