If production technology improves, how is the market supply curve affected in a perfectly competitive market?

$\mathrm{A}\left(\mathrm{g}\right)\rightleftharpoons 2 \mathrm{B}( \mathrm{g})+\mathrm{C}\left(\mathrm{g}\right)$

For the given reaction, if the initial pressure is $450 \mathrm{mmHg}$ and the pressure at time $\mathrm{t}$ is $720 \mathrm{mmHg}$ at a constant temperature$\mathrm{T}$ and constant volume $\mathrm{V}$. The fraction of $\mathrm{A}\left(\mathrm{g}\right)$ decomposed under these conditions is $\mathrm{x}\times {10}^{-1}$. The value of $\mathrm{x}$ is (nearest integer)

In the reaction ${\mathrm{PCl}}_5 \left(\mathrm{g}\right)\rightleftharpoons {\mathrm{PCl}}_3 \left(\mathrm{g}\right)+{\mathrm{Cl}}_2 \left(\mathrm{g}\right)$, which of the graphs is/are correct?

Among the following points indicated on the graph, which one represents equilibrium?

For the reaction $\mathrm{R}\rightleftharpoons \mathrm{P}$, variation of concentration is plotted against time. The time at which the equilibrium establishes is as shown:
