The table below shows the electronegativity values of various elements on the periodic tab; e. which pair of elements would form an ionic bond? ?

Which change to the system wood cause the freely-moving piston to lower?

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 is the rate law for the uncatalyzed reaction?
