Question

in a study of the decomposition of ammonia on a tungsten surface at 1100 °C

NH₃1/2 N₂ + 3/2 H₂

the concentration of NH₃ was followed as a function of time.

It was found that a graph of [NH₃] versus time in seconds gave a straight line with a slope of -5.24×10^-6 M s^-1 and a y-intercept of 7.41×10^-3 M.

Based on this plot, the reaction is order in NH₃ and the rate constant for the reaction is M s^-1
