Which of these two reactions would you expect to have the smaller orientation factor? explain. a. o( g) + n2( g)¡no( g) + n(g) b. no( g) + cl2( g)¡nocl( g) + cl( g)?

b. NO(g) + Cl_2( g) → NOCl(g) + Cl( g) has the smaller orientation factor.

If the Cl_2 attacks NO from the left: Cl-Cl + N-O → Cl + Cl-N-O. Wrong products!

If the Cl_2 attacks NO from the right: N-O + Cl-Cl → N-O-Cl + Cl. Correct products!

a. O(g) + N2(g) → NO(g) + N(g)

If an O atom attacks from the left: O + N-N → O-N + N. Correct products!

If an O atom attacks from the right: N-N + O → N + N-O. Correct products!

Reaction b. has the smaller orientation factor because the molecules have a smaller chance of colliding from the correct direction.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
