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

Which of the following reactions end in finite time?

If $c_o$ is the initial concentration of the reactant,what will be the half-life period for a zero-order reaction?

Which of the following is the incorrect equation for the rate constant of a zero-order reaction?

For a zero order reaction,$A \longrightarrow \text{product}$,the concentration of $A$ decreases from $1.2 \ mol \ dm^{-3}$ to $0.4 \ mol \ dm^{-3}$ in $240 \ s$. What is the rate constant of the reaction?

$5$ milli-moles of a solid $A$ was dissolved in $5$ moles of $H_2O$. On adding to the solvent,$A$ starts polymerising into another insoluble solid following zero order kinetics. On adding $6$ milli-moles of another solid solute $C$ (after $20$ minutes) the polymerisation completely stops. The insoluble solid polymer is removed and the resulting solution was cooled to a temperature less than $-0.186\,^{\circ}C$ (melting point of solution) to cause solidification of some liquid water. Calculate the value of $'X'$ if rate constant for polymerisation reaction is represented as $10^{-X}\,moles/minute$. $[K_f(H_2O) = 1.86\, K\, Kg\,mol^{-1}]$
