Consider this reaction: 2so2 (g) + o2 (g) 2so3 (g) + heat. what will happen if more sulfur trioxide gas is added to the reaction mixture?
a-the equilibrium will shift toward the products.
b-the equilibrium will shift toward the reactants.
c-keq will increase.
d-keq will decrease.
e-there will be no shift in equilibrium.

B-The equilibrium will shift toward the reactants.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

Given: when more is added

If the concentration of that is the product is increased, so according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease of concentration of takes place.

Therefore, the equilibrium will shift in the left direction or towards reactants.

okay yes , aha.

they are made of gases.

they have a spherical shape.

they make energy through fusion.
