Consider the hypothetical reaction: $A+BC+$ heat

What will happen to the concentrations of $A,B,C$ and temperature under each of the following conditions?

a$.,$ is added to the system, which is initially at equilibrium.

b$.$ C is removed from the system, which is initially at equilibrium.

c$.$ Either A or B is added to the system, which is initially at equilibrium.

d$.$ The system, which is initially at equilibrium, is cooled.

e$.$ The system, which is initially at equilibrium, is heated.
