At very high temperature hcl will decompose overtime to form gaseous hydrogen and chloride. The reaction is second order in hcl and the rate constant is 15.5x10-7m-1s-1 if the initial concentration of hcl is 0.200 m, what is the concentration of the remaining hcl after a reaction time of 1 week?

HCl. H2 + Cl2 ---> 2 HCl
Initiation: Cl2 + hv ---> 2 Cl ·
Propagation: Cl · + H2 ---> HCl + H· ;
H· + Cl2 ---> HCl + Cl ·
Termination: 2 H· ---> H2
2 Cl · ---> Cl2
H· + Cl · ---> HCl
The enthalpy for the initiation step is 243.36 kJ per mole of Cl2 which corresponds to the energy carried by light photons toward the violet end of the visible spectrum with a wavelength of 491.5 nm
