Hey There:
First order half life equation :
T 1/2 = ln ( 2 ) /K
T 1/2 = 0.693 / 3.40
T 1/2 = 0.204 s
Answer B
Answer: The half life of the decomposition reaction is 0.204 s
Explanation:
The equation used to calculate half life for first order kinetics:
[tex]t_{1/2}=\frac{0.693}{k}[/tex]
where,
k = rate constant of the reaction = [tex]3.40s^{-1}[/tex]
[tex]t_{1/2}[/tex] = half life of the reaction = ?
Putting values in above equation, we get:
[tex]t_{1/2}=\frac{0.693}{3.40s^{-1}}\\\\t_{1/2}=0.204s[/tex]
Hence, the half life of the decomposition reaction is 0.204 s
