The gases are contained in a reaction vessel and are in equilibrium at 298 K

X2Zi â 2XZ2(g)


a. Activation energy
b. Total mass of the system
c. Molar concentration of XZ4(g)
d. Number of molecules present
e. Equilibrium constant

1. Is decreased by the addition of a catalyst?
2. Is decreased when the volume of the reaction vessel is increased and equilibrium is reestablished at 298 K?

Answer :

Batolisisgo

Answer:

1) Activation energy  ( A )

2) Molar concentration of X[tex]_{2}[/tex]Z[tex]_{4}[/tex](g) ( C )

Explanation:

X[tex]_{2}[/tex]Z[tex]_{4}[/tex](g) ⇄ 2XZ

1) Activation energy Is decreased by the addition of a catalyst

while Equilibrium constant will Increase and other options will still remain unaffected

2)Molar concentration of X[tex]_{2}[/tex]Z[tex]_{4}[/tex](g) Is deceased when the volume of the reaction vessel is increased and equilibrium is reestablished at 298 K

while Number of molecules present will Increase
