Do we use half life for 0 order reactions or just 1st order?

The equation t1/2=0.693/k is only used for 1st order reactions.

The half life equation for a zero order reaction is [A0]/2k

theres different half life reactions for zero, 1st, and 2nd order. Only 1st order is independent of the concentration of A.
