The equilibrium can be affected when there is a change of concentration, pressure or temperature of the system. Since it is mentioned that the temperature is constant, and the parameter being focused on is the initial amount, that should be the concentration factor. It depends where substance X is placed in the reaction. If it is a reactant (left side), then the equilibrium would shift and favor the forward reaction. If it is a product (right side), then the equilibrium would shift and favor the reverse reaction.

Equilibrium quantities of Y and Z are directly affected by initial amount of X placed in container.

Further Explanation:

Le Chatelier’s principle:

According to this principle, if changes are done in pressure, temperature or concentration in any equilibrium reaction, equilibrium shifts to that direction in which effect of altered value is reversed.

Given reaction occurs as follows:

[tex]\text{2X(g)}\rightleftharpoons\text{Y(g)}+\text{Z(g)}[/tex]

From this reaction, it is evident that two moles of X decompose to produce one mole of Y and one mole of Z.

If amount of X used is large, it results in more formation of Y and Z and vice-versa. This implies amount of product formation depends on initial amount of X taken in reaction.

According to Le Chatelier's principle, if amount of X is increased, equilibrium will tend to shift in that direction in which more consumption of X is observed. This is done only if more products are formed. Opposite effects are observed in case less amount of X is taken. Hence formation of Y and Z is dependent on initial amount of X.
