Question

In 50 seconds a first order reaction is completed half, then what is its half-life? *​

Answer 1

Answer:

1386 seconds

Step-by-step explanation:

half life of first order reaction=0.693/k

where k is the rate constant or the spicifice rate constangive half life=1386 sec

0.693/k = 1386 sec

k =693/1386×10^-3

=0.5×10^-3 S^-1
