Calculate the limiting current for the hydrogen half-reaction, h+(aq) + e- = (1/2) h2(g), which takes place at an rde in hcl(aq) solution with ph=4 at 25 oc and 1 bar (latex: \nu ν = 10-6 m2/s), at an angular velocity of 100 rad/s. the diffusion coefficient of proton can be found in chapter 10: data section.

What is the molecular weight of copper

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.
