The gas phase decomposition of hydrogen iodide at 700 K

HI(g)½ H_{2}(g) + ½ I_{2}(g)

If the initial concentration of HI is 1.36 M, the concentration of HI will be M after 3.34E3 seconds have passed.

Thank you for the opportunity to help you with your question!

1/[A] = kt + 1/[A]o where k = 1.2 X 10^-3 t = 3.34 s [A]o = initial conc = 1.36 M [A] = conc.after 3.34 s 1/[A] = 1.2 X 10^-3 X 3.34 + 1/1.36 1/[A] = 4.74 so conc after 3.34 = 0.2109 M

correct can u answer this for me please!?

The decomposition of ammonia on a platinum surface at 856 °CNH_{3}1/2 N_{2} + 3/2 H_{2}is zero order in NH_{3} with a rate constant of 1.50E-6M s^{-1}.If the initial concentration of NH_{3} is 7.65E-3 M, the concentration of NH_{3} will be2.24E-3 M after seconds have passed.
