SO_(2)Cl_(2)hArrSO_(2)+Cl_(2) is the first order gas reaction with k=2.2xx10^(-5)sec^(-1) at 320^(@)C. The percentage of SO_(2)Cl_(2) decomposed on heating for 90 minutes is

Answer»

`1.118`
`0.1118`
`18.11`
`11.30`

Solution :`k=(2.303)/(t)log.(a)/((a-x))implieslog.(a)/((a-x))=(k.t)/(2.303)`
`implieslog.(a)/(a-x)=(2.2xx10^(-5)xx60xx60)/(2.303)=0.0516`
HENCE, `(a)/((a-x))=1.127implies(a-x)/(a)=0.887`
`implies1-(x)/(a)=0.887implies(x)/(a)=0.113=11.3%`
