Consider the given endothermic reaction at equilibrium,$PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$. $A$ graph is plotted between concentration and time as shown. Effect-$1$ and Effect-$2$ are due to respectively:

$A$ container at equilibrium contains $SO_3, SO_2$ and $O_2$. The total pressure in the container is increased while the temperature and volume remain constant. According to Le Chatelier's principle,the dissociation of $SO_3$ will........

The equilibrium constant for a reaction $A + B \rightleftharpoons C + D$ is $1 \times 10^{-3}$ at $298 \ K$ and is $2$ at $273 \ K$. The chemical reaction resulting in the formation of $C$ and $D$ is

What is the effect of increasing pressure on the dissociation of $PCl_5$ according to the equation $PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)} - x \ cal$?

The gas phase reaction $2NO_{2(g)} \rightleftharpoons N_2O_{4(g)}$ is an exothermic reaction. The decomposition of $N_2O_4$ in an equilibrium mixture of $NO_{2(g)}$ and $N_2O_{4(g)}$ can be increased by:
