The following gas-phase reaction, A + B ā C is carried out over a solid catalyst that has two different types of surface sites S and Sā. Experimental rate data is plotted in the figures below. What can you say given the figures above? Be sure to propose a mechanism and use it to derive a rate law consistent with the data. 1. Species A could be adsorbed on the surface but only very weakly adsorbed. 2. Species A is not adsorbed on the surface. 3. Species B is adsorbed to one type of site on the surface. 4. Species A is adsorbed to one type of site on the surface. 5. Species C is adsorbed on the surface. A. 1 and 2 are true. B. 3 and 4 are false. C. 1 and 4 are false. D. 4 and 5 are true. E. 2 and 5 are true

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
