I'm having a hard time figuring the following formula out. How is it applied? What does the |Ca=
Ca* suffix mean?
d(-1/Ra)/ dCa |Ca=Ca* = (1/-Ra,f - 1/-Ra* )/ (Ca* - Ca,o)
In the example I have to proof that for a first order reaction Ca*=(Ca,o*Ca,f)1/2
-Ra = k Ca
then I can rearrange d(-1/Ra) and everything containing -1/Ra to one side and everything containing concentrations to the other, but then, how do I integrate, what's with that suffix behind d(Ca)?
