The following $E(t)$ curve was obtained from a tracer test on a reactor.

$E(t)=0\mathrm{.}25t0t2$

$=1-0\mathrm{.}25t24$

The conversion predicted by the tanks$-$in$-$series model for the isothermal elementary reaction

$AB$ was $50\%$ at $300K.$ If the temperature is to be raised by $10C(E=25,000ca\frac{l}{m}ol)$ and

the reaction carried out isothermally, what will be the conversion predicted by the Tanks$-$in$-$

series model?

im stuck at calculating k
