A small patch of a catalyst surface is known to have 8 adsorption sites for gas molecules. What is the configurational entropy, S, when one Cl2 molecule and one Br2 molecule absorb on this patch of the surface? Give your answer to three significant figures.
Claisen reactions use a stoichiometric amount of base and do not polymerize, unlike aldol reactions that use a catalytic amount of base and can polymerize.
