Reaction would be 100 % complete only after infinite time which cannot be calculated.

Q. A first order reaction is $50%$ completed in $1.26 \times 1 0^{14} S .$ How much time would it take for $100%$ completion?

$1.26 \times 1 0^{15} S$

$2.52 \times 1 0^{14} S$

$2.52 \times 1 0^{28} S$

Infinite
