The half-life period for zero order reaction $A \rightarrow$ product, is 100 min. How long will it take in 80% completion?

(b)
For zero order reaction
$k = \frac{a}{2t_{1/2}} = \frac{a}{2 	imes 100} = \frac{a}{200}\$
When 80% completion take place
$\ k = \frac{x}{t}$
$\frac{a}{200} = \frac{0.80a}{t}$
$\ t = 200 	imes 0.8 = 160\ \min$
