If the initial concentration of a reactant is doubled,its half-life period also doubles. Determine the order of the reaction.

For a zero-order reaction,the ratio of $t_{1/2}$ to $t_{3/4}$ is ....

Which of the following statements is correct about a zero order reaction?

For a zero order reaction:

The reaction $2X \to B$ is a zeroth order reaction. If the initial concentration of $X$ is $0.2 \ M$,the half-life is $6 \ h$. When the initial concentration of $X$ is $0.5 \ M$,the time required to reach its final concentration of $0.2 \ M$ will be ........ $hr$.

$A$ zero order reaction is one whose rate is independent of
