For a first order reaction, the rate constant is expressed in terms of initial concentration CAo and final concentration CA as ____(a) CA = CAo × k(b) CA = CAo × e^-kt(c) CA = CAo × kt(d) CA = CAo × e^kt

Answer» The correct choice is (b) CA = CAo × e^-kt

The explanation: ((frac{-dC}{dt})) = kCA

ln((frac{CAo}{CA})) = kt

CA = CAo × e^-kt
