The values of pseudo-first-order rate constants (k (obs)) for the acetolysis of phthalic anhydride (PAn) increase from 6.60 x 10(-7) to 31.5 x 10(-7) s(-1) with the increase in temperature from 30 to 50 A degrees C. These values of k (obs) give activation parameters a dagger H* and a dagger S* as 14...
