Print Calculator Periodic Table Question 7 of 13 ncorrect Map Sapling Learning A generic gas, X, is placed in a sealed glass jar and decomposes to form gaseous Y and solid Z. ow are these equilibrium quantities affected by the initial amount of X(g) placed in the container? Assume constant temperature. Changes if initial Xl changes Constant regardless of initial [X] [X] at equilibrium mass of Z at equilibrium TYT at equilibrium [YVIX] at equilibrium [X] SITY] at equilibrium total pressure at equilibrium O Previous Next Give Up & View solution Check Answer Ext Hint

Explanation / Answer

here the reaction is given by 3X(g) = Y(g) + Z(s)

here if the initial concentration of X is varied then the concentration of X i.e [x] will be different as compared to the earlier value. and similarly the concentration of y i.e [y] will also vary accordingly

changing X means we are changing the moles of our reactant, hence the product will also change.

on the other hand the equilibrium constant is independent of the moles of the reactant undertaken and hence will remain unchanged. i.e the ration of [x]3 / [y] will remain constant even if we change the concentration of our reactant X.

mass of Z (s) will change accordingly to the moles of X taken intially, hence the mass of z will change if we increase or decrease the reactant concentration.

the ration of [y]/[x] will also change as the concentration of the reactant is changed. more concentration of x means the reaction will procede in the forward reaction creating more y and hence increasing its concentration and changing the ratio of [y]/[x]. only the ration of [x]^3/[y] remains fixed and not [y]/[x].

according to le chateliers principle if we change the concentration of the reactant, the reaction tend to shift in the forward direction, hence decreasing the concentration of x and incrasing the concentration of y. In this process if there are more moles of x initially the total pressure wll be more, if the moles or mass of x is less the total pressure will be less.
