Question

The decomposition of ammonia on a tungsten surface at 1100 °C

NH₃1/2 N₂ + 3/2 H₂

is zero order in NH₃.

In one experiment, when the initial concentration of NH₃ was 7.65×10^-3 M, the concentration of NH₃ dropped to 2.08×10^-3 M after 1.23×10³ seconds had passed.

Based on these data, the rate constant for the reaction is M s^-1.
