You are experimenting on the effect of temperature on the rate of reaction between hydrochloric acid (hcl) and potassium iodide (ki). when the reaction is completed at 400k there are approximately 250,000 collisions per mole of reactant. you run the experiment again at 150k. which of the following would you expect to be the number of collisions recorded at 150k a. 0 b. 400,000 c. 250,000 d. 15,000

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.
