Reaction intermediates differ from activated complexes in that:
a. they are stable molecules with normal bonds and are frequently isolate.
b. they are molecules with normal bonds rather than partial bonds and can occasionally be isolate.
c. they are intermediate with have characteristics of both reactants and products.
d. they are unstable and can never be isolated.
e. all reactions involve reaction intermediates, but not all have activated complexes.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.

What would be the original temperature of a gas that has a volume of 2.0 l and a pressure of 2.0 atm and an unknown temperature that the volume increased to 3.5 l in its pressure decreased to 1.0 atm if the final temperature is measured to be 11°c
