When a graph of concentration $\rightarrow$ Time is plotted for a zero order reaction,the value of the slope is . . . . . . .

For a certain reaction,$10\%$ of the reactant dissociates in $1 \ hour$,$20\%$ of the reactant dissociates in $2 \ hour$,and $30\%$ of the reactant dissociates in $3 \ hour$. What are the units of the rate constant?

For a reaction,doubling the concentration of the reactant doubles the half-life period. What is the order of the reaction?

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

If the initial concentration of a reactant is $a$,how much time will it take for a $100\%$ zero-order reaction to complete?

Half life of zero order reaction $A \rightarrow \text{product}$ is $1 \ \text{hour}$,when initial concentration of reactant is $2.0 \ \text{mol L}^{-1}$. The time required to decrease concentration of $A$ from $0.50$ to $0.25 \ \text{mol L}^{-1}$ is:
