What is Saponification? A process in which esters in fats are hydrolyzed with sodium or potassium hydroxide (NaOH or KOH) to produce a carboxylate anion which can act as a surfactant, i.e. soap.

Theory ,[object Object],[object Object],[object Object],[object Object],[object Object],-r A = kC A C B

More Theory ,[object Object],By combining these equations with the rate equation we get -r A = kC A C B -rA = kC Ao 2 (1-x A )( θ -x A ) C B = C Bo -C Ao x A

More Theory -rA = kC Ao 2 (1-x A )( θ -x A ) = dC A /dt Separating, Integrating, and Linearizing gives or and is in the form y=mx+b where C Ao ( θ -1)k is the slope of the line

More Theory ,[object Object],Once C A is determined, conversion can be calculated by which yields conversion at some time t Using all this information we can calculate k

More Theory ,[object Object],[object Object],[object Object],Plot 1/T vs lnk – if linear, then follows behavior
