The yellow solution of $Na_2CrO_4$ changes to orange red on passing $CO_2$ gas due to the formation of:

For the reaction $N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$,in which direction will the equilibrium shift if an inert gas is added at constant pressure?

$2B_{(g)} + 2C_{(g)} \rightleftharpoons 3A_{(g)} + \text{heat}$; necessary conditions to obtain high amount of $A$ are

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

Which of the following information can be obtained on the basis of Le Chatelier's principle?

For the reaction at equilibrium
$N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$
On addition of an inert gas at constant pressure and constant temperature,which of the following changes is $NOT$ observed?
