Consider the data given below for the hypothetical reaction $A \to X$:

$Time \ (s)$	$Rate \ (mol \ L^{-1} s^{-1})$
$0$	$1.60 \times 10^{-2}$
$10$	$1.60 \times 10^{-2}$
$20$	$1.60 \times 10^{-2}$
$30$	$1.60 \times 10^{-2}$

From the above data,the order of the reaction is:

For a zero order reaction,the plot of concentration $(a-x)$ $Vs$ time is linear with

The formation of gas at the surface of tungsten due to adsorption is a reaction of which order?

For a zero order reaction,which of the following statements is false?

The decomposition of $NH_3$ on the platinum surface is a zero-order reaction. If $K = 2.5 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$,what will be the rate of production of $H_2$ in $mol \ L^{-1} \ s^{-1}$ unit?

For a reaction of $n^{th}$ order,the plot of $t_{1/2}$ versus initial concentration $[A]_0$ is a straight line. When the initial concentration is $2 \ mol \ L^{-1}$,the reaction takes $10 \ min$ to complete $50\%$. If the reaction takes $t \ min$ to complete $50\%$ when the initial concentration is $4 \ mol \ L^{-1}$,find $n$ and $t$ respectively.
