A generic gas, X , is placed in a sealed glass jar and decomposes to form gaseous Y and solid Z . 3 X ( g ) − ⇀ ↽ − Y ( g ) + Z ( s ) How are these equilibrium quantities affected by the initial amount of X ( g ) placed in the container? Assume constant temperature

3 X ( g ) ⇄ Y ( g ) + Z ( s )

According to le chatelier principle increases in reactant concentration will shift equilibrium towrads right direction.

is constant with change in initial concentration of X.

Explanation:

                                      3 X ( g ) ⇄ Y ( g ) + Z ( s )

             Equilibrium constant for the reaction is as follows

                            =  

At equilibrium there is no change in the ratio of concentration of products to reactant if initial concentration change.

Therefore   is constant with change in initial concentration of X.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
