When intial concentration of the reactant is doubled ,the half-life period of a zero order reation………

Answer»

remains uncharged
is halved
is tripled
is doubled

Solution :For zero order reaction `t_((1)/(2))PROP[R]_(o)`
`t_((1)/(2))=K[R]_(0)`
If concentration is doubled .
`t_((1)/(2))(2)=K2[R]_(0)`
`therefore (t_((1)/(2))(2))/(t_((1)/(2)))=(K2[R]_(o))/(K[R]_(o))=2`
If concentration the reactant is double in a zero order reaction its half life TIME is doubled.
