Question

In the reaction below, how would adding more of reactant A offect the equilibrium of the system? (2 points)

A+B=C+D
Oa
Shift it to the right toward the products,
Oь
Shift it to the left toward the reactants,
Equally create more products and reactants,
It would have no effect

Answer 1

Shift it to the right toward the products,

Step-by-step explanation:

Adding more reactant will increase the concentration of the reactants, to offset this increased concentration, more products will be formed.

• An increase in concentration of a specie favors the direction that uses up that specie and lowers its concentration.
• If the concentration of the species on the LHS is increased , the equilibrium will shift to the right to maintain the constancy of the equilibrium constant.
