The effect of increasing the pressure on the equilibrium $2A + 3B \rightleftharpoons 3A + 2B$ is

What happens when a saturated solution of $CO_2$ is heated?

Explain: Effect of inert gas addition on equilibrium.

$(a)$ What is required in chemical synthesis? What will be done for that?
$(b)$ Write Le Chatelier's principle.

What is the effect of the reduction of the volume of the system for the equilibrium $2 C_{(s)} + O_{2(g)} \rightleftharpoons 2 CO_{(g)}$?

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