A → B is a first order reaction with rate 6.6 x 10-5 M s-1 . When [A] is 0.6 M, rate constant of the reaction is _______. (A) 1.1 x 10-5 s-1 (B) 1.1 x 10-4 s-1 (C) 9 x 10-5 s-1 (D) 9 x 10-4 s-1

Answer»

(B) 1.1 × 10–4 s –1

Rate = k[A]

∴ k = \(\frac{Rate}{[A]}=\frac{6.6\times10^{-5}}{0.6}\)

1.1 × 10–4 s –1
