The rate constant for the first order reaction is 60 ~s ⁻¹ . How much time will it take to reduce the concentration of the reactant to 1 16 th value?

Options

  1. A4.6 10⁻² ~s
  2. B4.6 10^4 ~s
  3. C4.6 10^2 ~s
  4. D4.6 10⁻⁴ ~s

Correct answer

A. 4.6 10⁻² ~s

Step-by-step solution

aligned t= 2.303 k & [A]₀ [A] & = 2.303 60 = a a 16 = 2.303 60 16 & = 2.303 60 1.204 & =0.0462 ~s =4.6 10⁻² ~s aligned
