The coefficients in a reaction equation are not necessarily equal to the reaction orders, whereas the coefficients of an elementary step always equal the reaction orders of its rate law. explain. 2. (8 pts) a reaction can be thermodynamically favorable, but kinetically unfavorable. what does that mean? when is a reaction thermodynamically or kinetically favorable or unfavorable? choose a suitable reaction and draw energy diagrams to explain these concepts. (8 pts) for a reaction the following mechanism was proposed: 3. (1) a+b c (fast) (2) c+d e (slow) (3) +b (fast) a. what is the overall equation? b. identify the intermediate(s) and catalyst(s), if any. c. what are the molecularity and the rate law for each step? d. is the mechanism consistent with the actual rate law: rate k[a][b][d]?

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
