What will most likely happen when a component is added to a reaction system at equilibrium?
a. the system will be unaffected by stress.
b. the addition of a catalyst will change the equilibrium.
c. the equilibrium position will shift away from what was added to lower its concentration.
d. the equilibrium position will shift away from what was added to increase its concentration.

C. The equilibrium position will shift away from what was added to lower its concentration.

1. Change in concentration.  

2. Change in pressure (caused by a change in volume).

3. Change in temperature.

The answer is c

im not exactly sure but i think its b!

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
