Identify the following statements as True $(T)$ or False $(F)$ for a zero-order reaction $R \to P$:
$(i) \ d[R] = -k dt$
$(ii) \ d[R] = +k dt$

$2A \xrightarrow{k} B$ is a zero-order reaction, where $k = 1.0 \text{ mol L}^{-1} \text{ min}^{-1}$. If the initial concentration of $A$ is $2 \text{ M}$, then the time taken to complete $75\%$ of the reaction will be (in $\text{ min}$)

Which of the following plots is correct for a zero-order reaction?

The rate constant of a zero-order reaction is $0.2 \ mol \ m^{-3} \ h^{-1}$. If the concentration of the reactant after $30 \ minutes$ is $0.05 \ mol \ m^{-3}$,then its initial concentration will be ....... $mol \ m^{-3}$.

The unit of rate constant for a zero order reaction is

Time required for $100\%$ completion of a zero order reaction is
