The conductivity probe measures current flow. It consists of two electrodes: one electrode is positively-biased, and the other is negatively-biased. Which respective directions do cations and anions flow when being measured?

options:

1) Both cations and anions flow to the positive electrode.

2) Both cations and anions flow to the negative electrode.

3) Cations flow to the negative electrode, and anions flow to the positive electrode.

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.
