The following data were given for thermal decomposition of `SO_2Cl_2` at a constant volume :
`SO_2Cl_(2)(g) to SO_2(g) + Cl_(2) (g)`

Calculate the rate of the reaction when total pressure is 0.65 atm.

Text Solution

Verified by Experts

`k=2.303/t "log"P_i/((2P_i-P_i))`
`=2.303/100 "log"0.5/((2xx0.5-0.6))`
`=2.303/100 "log"0.5/0.4`
`=2.303/100xx0.969=2.23xx10^(-3)s^(-1)`
Now , Rate =`P_(SO_2Cl_2)`
Pressure of `SO_2Cl_2` when total pressure =0.65 atm
`P_(SO_2Cl_2)=2P_i-P_t`
= 2 × 0.5 – 0.65
= 0.35 atm
Rate =`2.23xx10^(-3)xx0.35`
`=7.8xx10^(-4) "atm S"^(-1)`
