An industrial chemist is studying the rate of the haber synthesis: n2 + 3h2 → 2nh3. starting with a closed reactor containing 1.35 mol/l of n2 and 0.35 mol/l of h2, she finds that the h2 concentration has fallen to 0.12 mol/l after 50. seconds. what is the average rate of reaction of h2 over this time? (enter in mol/liter/sec). what is the average rate of nh3 production for this example? (enter in mol/liter/sec)

Cyrus Hardin · Answer 1

Average rate of reaction of H2 over this time is calculated as

initial concentration of H2 minus final concentration of H2

That is

{ (0.35mol/l - 0.12mol/l) / 50 sec} = 4.6 x 10 ^-3 mol/l/sec
