50.
In a zero order reaction, reactants concentration does not change with time and the
time for half change is half the time taken for completion of the reaction.
time for half change is independent of the initial concentration.
time for completion of the reaction is independent of the initial concentration.
reaction rate is trebled when the initial concentration is trebled.

For a zero-order reaction (r = k):
t1/2 = [A]0/2k
XA = kt/[A]0 .
@ completion, XA = 1 --> t = [A]0/k.

Comparing the two:
t1/2 = [A]0/2k.
t = [A]0/k.
t1/2 is half the value of t.
