If the system 3H2(g) + N2(g)   2NH3(g) is at equilibrium and more N2 is added, a net reaction that consumes some of the added N2 will occur until a new equilibrium is reached.
 

suppose the system is at equilibrium and more I2 is added. Describe what happens to Qc and explain which way the equilibrium will shift.

If a weak acid and a weak base are present in a solution, proton transfer will occur:

until equilibrium is reached

The reaction 2CH4(g)⇌C2H2(g)+3H2(g) has an equilibrium constant of K = 0.154. If 6.25 mol of CH4, 4.70 mol of C2H2, and 11.30 mol of H2 are added to a reaction vessel with a volume of 5.60 L , what net reaction will occur? The reaction has an equilibrium constant of = 0.154. If 6.25 of , 4.70 of , and 11.30 of are added to a reaction vessel with a volume of 5.60 , what net reaction will occur?

A - The reaction will proceed to the left to establish equilibrium.

B -The reaction will proceed to the right to establish equilibrium.

C -No further reaction will occur because the reaction is at equilibrium.
