Answer» Solution :`r_(INST)` is DETERMINED for any smallest time dt is as under . When `Deltat to0` or `r_(inst)=-(d[R])/(dt)=(d[P])/(dt)` So, dt =(When `Deltat` APPROACHES zero) For given Butyl chloride determine `r_(inst)=(d[C_(4)H_(9)Cl])/(dt)` ,draw graph of `[C_(4)H_(9)Cl]to t` (time) and determine the instantaneous rate by calculating the slope value of any time To calculate value of slope value of any time .That touches the curves and TAKE `DeltaR` and `Deltat` in graph.  If time t=600 sec. is TAKEN `r_(inst)(600s)=(0.0165-0.037 mol L^(-1))/((800-400)s)` If t=250 s then `r_(inst)(250)=1.22xx10^(-4)mol L^(-1)s^(-1)` If t=350 s then `r_(inst)(350)=1.0xx10^(-4)mol L^(-1)s^(-1)` If t=450 s then `r_(inst)(450)=6.4xx10^(-5)mol L^(-1) S^(-1)` |
