Explanation / Answer

Ans. # Note that the value of half-life remains constant irrespective of the initial concertation. It is characteristic of first-order kinetics.

Therefore, order of reaction = 1

# Half-life of first order reaction, t½ = 0.693 / k

            Or, k = 0.693 / t½                                        - equation 2

            Where, k = rate constant

            Or, k = 0.693 / 179s

            Hence, k = 3.87 x 10-3 s-1
