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]?

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
