Question

Calculate half life time of a 1st order reaction
having K = 4
1
min−.​

Answer 1

k=4

by the relation

t1/2=0.693/k

=0.693/4

0.1732s

I hope it is helpful to you

Answer 2

for first order reaction,

$t_\frac{1}{2}=0.693/k$

putting the vakue of k,

we get,

t½ = 0.693/4

=> t½ = 0.17325 second
