Given information

The half-life of the reaction gets longer as the initial concentration
is increased.

Step-by-step explanation

Step 1.
The half-life of the reaction gets longer as the initial concentration
is increased.
 
That means half-life and initial concentration are directly related.
 
Hence the reaction is zero order as,
 
For a zero order reaction half life expression is:
 
 
 
where,
k is the rate constant.
[A]0 is the initial concentration.
and t1/2 is the half-life.
