Math Problem Statement
Untuk reaksi orde pertama: A -> P maka v = −∆A/∆t=k[A]. Jabarkan persamaan laju tersebut dengan metode integral sehingga menemukan persamaan hukum laju : ln[A]t = −kt + ln[A]0 b. Gambarkan kurva ln[A}t versus t c. Jika waktu yang diperlukan agar separuh dari Zat A berubah menjadi P disebut t1/2, jabarkan lebih lanjut hukum laju pada jawaban (a) di atas untuk membuktikan bahwa t1/2 = 0,693/k. d. Berapa waktu paruh dari N2O5 jika terurai dengan konstanta laju 5.7 x 10-4 s-1?
