The decomposition of no2(g) occurs by the following bimolecular elementary reaction.
2 no2(g) → 2 no(g) + o2(g)

the rate constant at 273 k is 2.3 ✕ 10-12 l/mol · s, and the activation energy is 111 kj/mol. how long will it take for the concentration of no2(g) to decrease from an initial partial pressure of 2.8 atm to 1.2 atm at 495 k? assume ideal gas behavior.

Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
