Answer 1

Answer:

Calculate the half-life of a first order reaction from their rate constants given below: (i) 200 s-1. (ii) 2 min-1. (iii) 4 years-1. Answer. (i) Half life, t½ = 0.693 / k. = 0.693 / 200 s-1. = 3.47 ×10 -3 s (approximately)

Answer 2

Answer:

Hola‼.....✌

(i) Half life, t½ = 0.693 / k

= 0.693 / 200 s-1

= 3.47 ×10 -3 s

(ii) Half life, t½ = 0.693 / k

= 0.693 / 2 per min

= 0.35 min
