Which of the following is the slope of the graph of $[A]_{t}$ versus time for a zero order reaction?

The rate constant for a zero order reaction is $2 \times 10^{-2} \ mol \ L^{-1} \ sec^{-1}$. If the concentration of the reactant after $25 \ sec$ is $0.5 \ M$,the initial concentration must have been ......... $M$.

What is the unit of $K$ for a zero-order reaction?

For a reaction $A \to$ Products,a plot of $\log\,t_{1/2}$ versus $\log\,a_0$ is shown in the figure. If the initial concentration of $A$ is represented by $a_0,$ the order of the reaction is

The rate constant of a zero order reaction is $2.0 \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$. If the concentration of the reactant after $25 \ s$ is $0.5 \ M$,then find the initial concentration of the reactant. (in $M$)

The rate constant,$k$ of a zero order reaction $2 NH_{3(g)} \xrightarrow[1130 \ K]{Pt} N_{2(g)} + 3 H_{2(g)}$ is $y \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$. The rate of formation of hydrogen (in $mol \ L^{-1} \ s^{-1}$) is
