Half life of a zero order reaction is directly proportional to $\qquad$

$A \rightarrow P$ is a zero order reaction. At $298 \ K$ the rate constant of the reaction is $1 \times 10^{-3} \ mol \ L^{-1} \ s^{-1}$. Initial concentration of '$A$' is $0.1 \ mol \ L^{-1}$. What is the concentration of '$A$' after $10 \ s$?

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

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

Mention True $(T)$ and False $(F)$ statements for the following regarding a zero-order reaction $R \rightarrow P$:
$1. \ t_{1/2} \propto [R]_0$
$2. \ t_{1/2} \propto k$

If the rate of the reaction is equal to the rate constant,the order of the reaction is
