An equilibrium system is established in a $1\mathrm{.}00L$ flask at $800C,$ as represented by the following equation:

$2C{H}_4(g)C_2{H}_2(g)+3H_2(g),{}_{r}H=+302kJ$

A technician disturbed the above equilibrium with four different stresses and graphed the results. Match the graphs with the stresses listed

$1$ system was cooled $2$ added CH$4($g$)2$ removed CH$4($g$)5$ decrease the pressure
