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

Write the rate equation for the reaction $2A + B \to C$ if the order of the reaction is zero.

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

Mention True $(T)$ and False $(F)$ statements for the following expressions related to a zero-order reaction $R \to P$:
$I. \ k = \frac{[R]_0}{2 t_{1/2}}$
$II. \ t_{1/2} = \frac{[R]_0}{4k}$

In the reaction,$A \rightarrow$ products,if the concentration of the reactant is doubled,the rate of the reaction remains unchanged. The order of the reaction with respect to $A$ is

For the reaction $A \longrightarrow 3 B$,the rate is given by $rate = k[A]^0$. Based on the data provided in the table,what is the concentration of the product $B$ (in $mol \ L^{-1}$) after $20 \ s$?

Time $(s)$	Concentration of the reactant $(mol \ L^{-1})$
$0$	$0.1$
$15$	$0.05$
$20$	$0.1 - x$
