Pembahasan

Persamaan laju reaksi seperti itu menyatakan hubungan antara konsentrasi pereaksi dengan laju reaksi. Persamaan lajunya maka: Menentukan nilai k dengan mengambil salah satu laju reaksi yaitu yang pertama. Nilai k yaitu 10 M -2 s -1 . Menentukan nilai x yaitu: Nilai x yaitu 0,4 M/detik. Jadi, dapat disimpulka n nilai x yaitu 0,4 M/detik.
