In a study of the decomposition of hydrogen iodide on a gold surface at 150 °C HI(9)-Va H2(9) + V½ I2(9) the concentration of HI was followed as a function of time. It was found that a graph of (HI] versus time in seconds gave a straight line with a slope of -1.92×104M s²ª and a y-intercept of 0.260 M. Based on this plot, the reaction is order in HI and the rate constant for the reaction is In a study of the gas phase decomposition of dinitrogen pentoxide at 335 K N2Os(9)2 NO¿(9) + V½ Oz(9) the concentration of N20s was followed as a function of time. It was found that a graph of In[N205] versus time in seconds gave a straight line with a slope of -6.35x10 s1 and a y-intercept of -2.7s. Based on this plot, the reaction is order in N3os and the rate constant for the reaction is

In a study of the decomposition of hydrogen iodide on a gold surface at 150 °C
HI(9)Va H2(9) + Va I2(9)
the concentration of HI was followed as a function of time.
It was found that a graph of (HI] versus time in seconds gave a straight line with a slope of -1.92x104 Ms1 and a
y-intercept of 0.260 M.
Based on this plot, the reaction is
order in HI and the rate constant for the reaction is
Ms
In a study of the gas phase decomposition of dinitrogen pentoxide at 335 K
N20s(9)2 NO2(9) + V½ O2(9)
the concentration of N20s was followed as a function of time.
It was found that a graph of In[N20s] versus time in seconds gave a straight line with a slope of -6.35x10 s1 and a
y-intercept of -2.7s.
Based on this plot, the reaction is
order in N20s and the rate constant for the reaction is
