The decomposition of gaseous Cl(2)O(7) ...

The decomposition of gaseous `Cl_(2)O_(7)` to gaseous `Cl_(2) and O_(2)` at 400K is a first order reaction . After 55 s , the pressure of `Cl_(2)O_(7)` falls from 0.062 to 0.044 atm . Calculate
the rate constant

Text Solution

Verified by Experts

`Cl_(2)O_(7)rarrCl_(2)+(7)/(2)O_(2)`
`k = (2.303)/(t)log.(P_(i))/(P_(t))`
`therefore k = (2.303)/(55)log(0.062)/(0.044)=6.2xx10^(-3)s^(-1)`
