The gas phase decomposition of hydrogen iodide at 700 K
HI(g)½ H2(g) + ½ I2(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 °CNH31/2 N2 + 3/2 H2is zero order in NH3 with a rate constant of 1.50E-6M s-1.If the initial concentration of NH3 is 7.65E-3 M, the concentration of NH3 will be2.24E-3 M after seconds have passed.
