A generic gas, X , is placed in a sealed glass jar and decomposes to form gaseous Y and solid Z . 2 X ( g ) − ⇀ ↽ − Y ( g ) + Z
tamaranim1 [39]

Answer:

The equilibrium will go right, increasing the quantities of Y(g) and Z(s), when the amount of X(g) increases.

Explanation:

Equilibrium is a state in which the velocity of the formation of the products is equal to the velocity of the formation of the reactants. Thus, the concentrations remain constant.

By Le Chatêlier's principle, when the equilibrium is disturbed, the equilibrium must shift to reestablish the equilibrium. Thus, when X is put in the container, it intends to decompose and form Y and Z, thus, as higher is the initial X, as higher is the Y and Z formed.
