`{:("Experiment","Time (s)","Total Pressure (atm)"),(1,0,0.3),(2,100,0.5):}`
`SO_(2)Cl_(2)(g)rarrSO_(2)(g) + Cl_(2)(g)`
`k=(2.303)/(t) log .(P_(0))/(2P_(0)-Pt)" "[P_(0) - "initial pressure Pt = Pressure at 't' time]"`
When, `t=100sec, k = (2.303)/(100) log.(0.3)/(2xx0.3-0.5) implies k = (2.303)/(100) log.(0.3)/(0.1)`
`k=(2.303)/(100)log3 " "implies k = (2.303)/(100) xx 0.4771`
` k = 0.0109 S^(-1)`
