A unimolecular irreversiable $1$st order reaction. $$A|$rightarrow $R$$$.$ To determine its reaction constant, concentration $(CA,mo\frac{l}{d}m3)$ over time $(t,$min$)$ was measured, and we plot the data where $log(C\frac{A}{C}A0)$ is $y-$axis, and $t$ is $x-$axis, as shown below. How many percent of reactant A will be remained after $5$ minutes of reaction?
