Strategy for Kinetics Equations with Gases

My concentration equation like [A]=-kt+[A]_0

What is the strategy for converting this in terms of pressure?

Lets say we are given P_0 in mm Hg and half lives in minutes

My guess is that [A] is proportional to P, one of those but I am unsure what the proportionality constant is or how it affects the half life formulas.

What is the strategy for converting this in terms of pressure? How do rederive kinetics expressions with pressures?

It is a matter of applying Avogadro's law.
