Question

When initial concentration of the reactant is doubled, the half-life period of a zero order reaction
A. is halved
B. is doubled
C. is tripled
D. remains unchanged

Answer 1

Correct Answer - B
`(t_(1//2))_(zero) = ([A]_(0))/(2K)` for zero order `t_(1//2) prop [A_(0)]^(1)`
`:.` If `[A]_(0) =` doubled, `t_(1//2) =` doubled.
