Answer:
(a) 0.8 s
(b) t = 7.2 s
Explanation:
(a) Half life expression for second order kinetic is:
Where,
is the initial concentration = 1.0 M
k is the rate constant = 1.25 M⁻¹s⁻¹
So,
Half life = 0.8 s
(b) Integrated rate law for second order kinetic is:
Where, is the final initial concentration
For 90% completion, 10% is left. so,
So,
t = 7.2 s
