In a zero-order reaction, if the initial concentration of the reactant is doubled, the time required for half the reactant to be consumed

Options

A. increase two-fold
B. increases four-fold
C. decreases by half
D. does not change

Answer

A

Explanation

`K=(A_(0)-A_(t))/(t)`
`K=A_(2)/(2t_(1//2))`
`t_(1//2)=A_(0)/(2K)` Zero order
`t_(1//2) prop` initial concentration
so double times
